## Settings Hierarchy

tabi has a hierarchy that allows you to customise your site at different levels. The hierarchy (from low to high priority) is as follows:

1. Global settings: These are the settings that apply to your entire site. They are set in `config.toml`.
2. Section settings: These are the settings that apply to a section of your site (e.g.`/blog` or `/projects`). They are set in the front matter of the `_index.md` file of the section.
3. Parent page settings: For nested pages (pages within pages), these are the settings from the parent page.
4. Page settings: These are the settings that apply to a single page. They are set in the front matter of the page.

In all cases, tabi’s settings are set in the `[extra]` section.

For settings which follow this hierarchy, the value set on a page overrides the value for a section, which overrides the global value. In short: the more specific the setting, the higher priority it has, or `page > parent page/section > config.toml`.

## Search

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ✅

tabi supports accessible, local multi-lingual search with Elasticlunr. To enable it, you need to:

1. Set a `default_language` in `config.toml`.
2. Set `build_search_index = true`.
3. Optionally, configure the `[search]`.

Here’s an example configuration:

    base_url = "https://example.com"
    default_language = "en"
    build_search_index = true

    [search]
    index_format = "elasticlunr_json" # Or the less efficient "elasticlunr_javascript".
    include_title = true
    include_description = true
    include_path = true
    include_content = true

Note: for Chinese/Japanese search support, you need to use a custom Zola build.

### Considerations for Zola 0.17.X Users

Zola 0.17.X doesn’t provide access to the `search.index_format` variable (bug report). When using tabi, this variable defaults to the more efficient JSON index. However, due to another bug fixed in 0.18.0, the JSON index for multi-language sites is not generated correctly.

Users with Zola versions prior to 0.18.0 who want to use the JavaScript index need to set the `index_format` variable in two places:

    [search]
    index_format = "elasticlunr_javascript"

    [extra]
    index_format = "elasticlunr_javascript"

This ensures tabi loads the right files. We recommend upgrading to Zola 0.18.0 or later for optimal functionality.

### Implementation Details

For technical details about the search implementation in tabi, including when the index loads, accessibility features, and other specifics, see the Pull Request #250.

## Multilingual Support

tabi offers comprehensive multilingual support for your Zola site, from setting a default language to adding as many as you wish. Refer to the multilingual FAQ for more information.

## Appearance

### Home Page

The main page of this demo has a header with an image, a title and description:

#### Heading

To set the image and title, you can use the `header` variable in the front matter of the section’s `_index.md` file. For example:

    [extra]
    header = {title = "Hello! I'm tabi~", img = "img/main.webp", img_alt = "Óscar Fernández, the theme's author" }

The description is regular Markdown content, set outside the front matter.

#### Listing Recent Posts

To show posts on your main page, you first need to decide where these posts will be served from: the root path (`/`) or a subdirectory (e.g., `/blog`).

Option A: Serve posts from the root path (`/`)

Set `paginate_by` in the front matter of your `content/_index.md` file:

    title = "Latest posts"
    sort_by = "date"
    paginate_by = 5  # Show 5 posts per page.

    [extra]
    header = {title = "Hello! I'm tabi~", img = "img/main.webp", img_alt = "Your Name" }

NOTE

The `paginate_by` setting goes in the main front matter, not in the `[extra]` section.

Option B: Serve posts from a subdirectory (e.g., `/blog`)

Use `section_path` in the `[extra]` section of your `content/_index.md` file:

    title = "Latest posts"
    sort_by = "date"
    # Do not set `paginate_by` here.

    [extra]
    header = {title = "Hello! I'm tabi~", img = "img/main.webp", img_alt = "Your Name" }
    section_path = "blog/_index.md"  # Where to find your posts.
    max_posts = 5  # Show up to 5 posts on the main page.

WARNING

Do not set both `paginate_by` and `section_path`. These settings are mutually exclusive and using both may result in no posts being displayed.

Additional notes:

- The `title` in the front matter sets the header that appears above the posts.
- Use the full path to the section’s `_index.md` file for `section_path`. Using `section_path = "blog/"` will not work.

##### Pinning Posts

You can pin posts to keep them at the top of the main page listing. In this demo, this post is pinned, so it appears first with a “pinned” icon and label:

Pinned posts are shown first, maintaining their relative order of the section’s `sort_by`, followed by regular posts.

To pin a post, add the following to its front matter:

    [extra]
    pinned = true

INFO

This setting only affects your site’s main pages (like `/`, `/es/`, `/fr/`). Other sections like `blog/`, `tags/`, or `archive/` show posts in their normal order.

WARNING

When using pagination (`paginate_by`), pinned posts may appear twice: once on top of page 1, and again in their normal chronological position on subsequent pages.

##### Display the Date of Posts in Listing

By default, when listing posts, the date of post creation is shown. You can configure which date(s) to display using the `post_listing_date` option. Available settings:

- `date`: Show only the original date of the post (default).
- `updated`: Show only the last updated date of the post. If there is no last updated date, it shows the original date.
- `both`: Show both the original date and the last updated date.

    post_listing_date = "date"

TIP

This setting follows the hierarchy: you can set a global value in `config.toml` or override it for specific sections in their `_index.md` file. In both cases, add it to the `[extra]` section.

#### Listing Projects

You can showcase a selection of projects on your main page. To do this, you’ll need to set up the `projects` directory first.

Once that’s done, you configure the path to the projects in the `[extra]` section of your `_index.md` file:

    [extra]
    projects_path = "projects/_index.md"

By default, this will show the 3 projects with the highest priority (smallest weight; same sorting as Projects page). To show more or fewer projects, you can set `max_projects` in the `[extra]` section.

By default, the featured projects will be shown after the posts. If you want to show the projects before the posts, set `show_projects_first = true`.

### Light and Dark Mode Switcher

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ✅

The light and dark mode switcher (the moon/sun icon on the top right) can be enabled by setting `theme_switcher = true` in `config.toml`.

### Default (Light/Dark) Mode

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

The default theme can be specified with the `default_theme` variable, which accepts either `"dark"` or `"light"`. If you don’t set it, the default theme will be the one set in the user’s browser.

### Custom Skins

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

tabi’s skins change the main colour of the site. You can set the skin in `config.toml` with `skin = "skin_name"`. For example, `skin = "lavender"` looks like this (click to switch between light and dark mode):

Explore the available skins and learn how to create your own reading the documentation.

### Sans-serif Font

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

tabi uses a serif font for article paragraphs (the one you’re seeing now). You can switch to using a sans-serif font (the one on the headers/menu) throughout your entire site by setting `override_serif_with_sans = true` in your `config.toml`.

Click on the image below to compare the two looks:

### External Link Indicator

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

INFO

Requires Zola 0.20.0 or later.

If you’d like to add an icon to external links, configure the `[markdown]` (not `[extra]`) section in your `config.toml`:

    [markdown]
    external_links_class = "external"

This will add a small icon next to external links:

### Custom CSS

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ❌ | ✅ | ❌ | ❌

You can load custom CSS for the entire site or on specific pages with `stylesheets`, which takes a list of paths to CSS files. For example:

    stylesheets = ["css/custom.css", "css/another.css"]

### Browser Theme Colour

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

The browser theme colour is the colour that appears in the browser’s tab bar:

You can set it in `config.toml` like `browser_theme_color = "#087e96"`. If you’d like different colours for dark/light mode, you can set an array of colours with `browser_theme_color = ["#ffffff", "#000000"]`. The first colour will be used for light mode, the second for dark mode.

This variable accepts any valid CSS colour, so you can use keywords (e.g. `blue`), hex codes (e.g. `#087e96`) or RGB/HSL values (e.g. `rgb(8, 126, 150)`).

### Compact Tags

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

By default, the tags page displays tags as:

TagName — n post[s]

Setting `compact_tags = true` will display them as:

TagName n

### Tags Sorting

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

By default, the tags page sorts tags alphabetically, given the default setting of `tag_sorting = "name"`.

Setting `tag_sorting = "frequency"` will sort them by number-of-posts (descending).

## Series

For a detailed explanation of the series feature, see the series documentation.

### Jump to posts link

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ✅ | ✅ | ✅ | ❌

By default, a “Jump to posts” link automatically appears next to the series title when a series has a content over 2000 characters:

Set `show_jump_to_posts = true` to force the feature on and `show_jump_to_posts = false` to force it off.

### Series pages indexation

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ✅ | ✅ | ✅ | ❌

By default, series page are indexed (using a 1-based indexing) as per the series section `sort_by`.

Set `post_listing_index_reversed = true` to reverse this index.

## Git Repository Integration

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❓ | ❓ | ✅ | ❓ | ❌

❓: `show_remote_source` does follow the hierarchy and can be set on a page, section or globally. The rest of the settings can only be set in `config.toml`.

These settings allow you to link your tabi website with a public Git repository in GitHub, GitLab, Gitea or Codeberg. Example settings:

    remote_repository_url = "https://github.com/welpo/tabi"
    remote_repository_git_platform = "auto"
    remote_repository_branch = "main"
    show_remote_changes = true
    show_remote_source = true

This enables two features:

1. `show_remote_source = true` adds a link to the source code of your site (your `remote_repository_url`) will be displayed on the footer:

1. `show_remote_changes = true` adds a “See changes ↗” link to the commit history of updated posts, next to the last updated date 1:

Clicking on this link will take you to the commit history of the post, where you can see the changes made to it:

## Pages

### Projects

tabi has a built-in projects (cards) template. To enable it, you can create a directory in `content/projects/`. There, you can create a `_index.md` file with the following front matter:

    title = "Projects"
    sort_by = "weight"
    template = "cards.html"
    insert_anchor_links = "left"

    [extra]
    show_reading_time = false
    quick_navigation_buttons = true

- The `title` is the title of the page.
- `sort_by` determines how the projects are sorted. You can sort by “date”, “update_date”, “title”, “title_bytes”, “weight”, “slug” or “none”.
- `template = "cards.html"` sets the template to render the projects page.
- `insert_anchor_links = "left"` adds anchor links to headers.
- `show_reading_time = false` hides the reading time.
- `quick_navigation_buttons = true` shows the quick navigation buttons are shown.

Alongside the `_index.md` file, you can create a file for each project. For example, this is the front matter for the tabi project page:

    title = "tabi"
    description = "A feature-rich modern Zola theme with first-class multi-language support."
    weight = 1

    [extra]
    local_image = "img/tabi.webp"

- `title` is the title of the project.
- `description` is the description of the project.
- `weight` determines the order in which the projects are shown. The lower the weight, the higher the project will appear.
- `local_image` is the path to the image of the project. This image is shown on the projects page.

When a user clicks on the image or title of a project, they will be taken to the project’s page. If you’d rather have users go to an external link, you can set `link_to = "https://example.com` in the `[extra]` section of the project’s `.md` file.

The individual project’s page is rendered with the default template, unless you set another one, e.g. `template = "info-page.html"`.

#### Filtering Projects

If you add tags to your projects, you will see a tag filter:

The tag filtering system uses progressive enhancement:

- Without JavaScript: Tags link directly to dedicated tag pages (e.g. `/tags/tag-name`)
- With JavaScript: Instant filtering, URL syncing (#tag-name), and keyboard navigation

To disable this feature, set `enable_cards_tag_filtering = false` in the `[extra]` section of the `projects/_index.md` file or in `config.toml`.

TIP

To filter projects by tags, you need to set tags in the front matter of each project. For example:

    title = "project name"
    weight = 40

    [taxonomies]
    tags = ["tag one", "tag 2", "third tag"]

### Archive

Adding an archive page is similar to adding a projects page. You can create a directory in `content/archive/`. There, you can create a `_index.md` file with the following front matter:

    title = "Archive"
    template = "archive.html"

By default, the archive will list posts located in `blog/`. To customise this, you can modify the `[extra]` section of the `_index.md` file:

- For a single source path: Set `section_path = "your-path/"` to list posts from a specific directory. Make sure to include the trailing slash.

- For multiple source paths: If you want to aggregate posts from various directories, `section_path` can be specified as a list of paths. For example:

      [extra]
      section_path = ["blog/", "notes/", "path-three/"]

The archive displays posts in reverse chronological order (newest first). You can reverse this order by setting `archive_reverse = true` in the `[extra]` section:

    [extra]
    archive_reverse = true  # displays oldest posts first.

NOTE

The Archive page will only list posts that have a date in their front matter.

### Tags

tabi has built-in support for tags. To enable them, simply add the taxonomy to your `config.toml`:

    taxonomies = [{name = "tags", feed = true}]

You can then add tags to your posts by adding them to the `tags` array in the front matter of your post. For example:

    title = "Bears, Beets, Battlestar Galactica: The Dwight Schrute Guide to Life"
    date = 2007-04-26
    description = "Lessons learned from beet farming and paper sales."

    [taxonomies]
    tags = ["personal", "beets"]

### About Page

If you’d like to have a non-article page for an “About” section, a “Contact” or “Copyright” page, etc., you can use the `info-page.html` template.

First, create a directory inside `content/` with any name you like. For example, `content/pages/`. Then, create a `_index.md` file inside that directory. The file should look like this:

    +++
    render = false
    insert_anchor_links = "left"
    +++

- `render = false` tells Zola not to render the section.
- `insert_anchor_links = "left"` adds anchor links to headers. This is optional.

Inside the directory, you can create any number of `.md` files.

In this demo, the about page uses the `info-page.html` template. The front matter is as follows:

    title = "About"
    template = "info-page.html"
    path = "about"

Notice how the `path` is set to `about`. Zola will place the page at `$base_url/about/`. If you’d like to have the page available at `/contact/`, you’d set `path = "contact"`.

The `info-page.html` template can also be used to create landing pages at the path root (`"/"`). To do that, the `content/_index.md` file should look like this:

    +++
    title = "Landing Page Title"
    template = "info-page.html"
    +++

    Place your landing page Markdown content here.

## SEO

tabi takes care of most of the SEO for you (like Open Graph protocol tags, description, color-scheme…), but there are a few things you can customise.

### Favicon

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

The favicon is the small icon that appears in the browser tab. You can set it in `config.toml` with `favicon = "img/favicon.png"`.

### Emoji Favicon

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

You can also set an emoji as your favicon with `favicon_emoji`. For example, `favicon_emoji = "👾"`.

Note: Some browsers don’t support emoji favicons. See the compatibility table in caniuse.

### Canonical URL

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ❌ | ❌

The canonical URL is a way to indicate to search engines what the preferred URL is for your website content. This is useful for SEO and avoiding duplicate content issues.

By default, the canonical URL is the URL of the page you’re on. However, you can override this by setting `canonical_url` in the front matter of your page or section.

If you have a site with an identical structure and matching content, you can set `base_canonical_url` in your `config.toml`. The canonical URL will be crafted by replacing the `$base_url` of the current URL with the `$base_canonical_url` you set.

For example, if you set `base_canonical_url = "https://example.com"`, the canonical URL of the page `$base_url/blog/post1` will be `https://example.com/blog/post1`. This is useful if you have a site with multiple domains that share the same content.

Note: to ensure that the canonical URL is correct, it’s probably best to set `canonical_url` individually for each page.

### Social media cards

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

Social media cards are the images that are displayed when you share a link on social media:

You can set the social media image with `social_media_card = "img/social_media_card.png"`.

You can specify both relative and absolute paths.

- Relative Path: Place the image in the same folder as your blog post and specify its name. For example, `social_media_card = "relative_image.png"`.

- Absolute Path: Put the image in a specific folder and specify the path from the root. For example, `social_media_card = "/img/absolute_image.png"`.

If both relative and absolute paths are valid, the relative path will take precedence.

Since it follows the hierarchy, if it’s not set on a page, but is set on a section, the section’s image will be used. If it’s not set on a page or section, but is set in `config.toml`, the global image will be used.

PROTIP

### Fediverse Creator

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

You can highlight your fediverse profile in Mastodon link previews by setting the `fediverse_creator` variable in your `config.toml`. For example, for @username@example.com, use:

    fediverse_creator = { handle = "username", domain = "example.com" }

This adds metadata to your HTML, allowing Mastodon to display the author’s fediverse profile when your content is shared.

## Navigation

### Navigation Bar

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

The navigation bar is the bar at the top of the page that contains the site title and the navigation menu. You can customise which items appear by setting `menu` in `config.toml`.

The menu supports both relative URLs for internal pages and absolute URLs for external links. For example:

    menu = [
        { name = "blog", url = "blog", trailing_slash = true },
        { name = "archive", url = "archive", trailing_slash = true },
        { name = "tags", url = "tags", trailing_slash = true },
        { name = "projects", url = "projects", trailing_slash = true },
        { name = "about", url = "about", trailing_slash = true },
        { name = "github", url = "https://github.com/welpo/tabi", trailing_slash = false },
    ]

### Quick Navigation Buttons

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

Quick navigation buttons are the buttons that appear on the bottom right of the screen. You should see them on this page, if you’re not on mobile. They look like this:

The buttons allow you to quickly navigate through an expandable mini-table of contents, to the comment section (if enabled), as well as to the top of the page.

To enable them, set `quick_navigation_buttons = true`.

### Table of Contents

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

Enable the table of contents right below the post’s title and metadata with `toc = true`.

Read more about the table of contents and how to customise it by reading the docs.

### Previous and Next Article Links

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

Displays links to the previous and next articles at the bottom of posts. It looks like this:

To activate this feature, set `show_previous_next_article_links = true` and ensure your section has a `sort_by` value (e.g. `sort_by = "date"`).

By default, next articles will be on the left side of the page and previous articles will be on the right side. To reverse the order (next articles on the right and previous articles on the left), set `invert_previous_next_article_links = true`.

By default, this navigation section will have the full width of the site (same as the navigation bar at the top). To make it narrower, matching the article width, set `previous_next_article_links_full_width = false`.

All of these settings follow the hierarchy.

### Footnote Backlinks

DEPRECATION WARNING

Zola v0.19.0 and later can do this natively. Set `bottom_footnotes = true` in your config’s `[markdown]` section.

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ✅

Setting `footnote_backlinks = true` will add backlinks to the footnotes of your posts, like this:

When you click on a backlink (the arrow ↩), it will take you back to the text where the footnote was referenced.

## Usability

### Copy Button on Code Blocks

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ✅

Setting `copy_button = true` will add a small copy button to the top right of code blocks, like this:

### Clickable Code Block Names

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ✅

Setting `code_block_name_links = true` enables URLs in code block names to become clickable links. Check out the documentation for examples and usage.

### Force Code Blocks LTR

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

By default, code blocks are rendered left-to-right, regardless of the overall text direction. Set `force_codeblock_ltr = false` to allow code blocks to follow the document’s text direction. Useful for RTL languages needing RTL code blocks.

### KaTeX Support

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ✅

KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web. You can enable it with `katex = true`. See what it looks like in tabi here.

### Mermaid Support

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ✅

Mermaid is a JavaScript-based diagramming and charting tool. You can enable it with `mermaid = true`.

By default, the Mermaid library is served locally. If you prefer to use a CDN, set `serve_local_mermaid = false` in `config.toml`. Using a CDN will serve the latest version of Mermaid; the local option will serve the version bundled with tabi.

See the Mermaid documentation for usage instructions and examples.

### Custom Font Subset

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

Custom fonts cause flashing text in Firefox. To amend this, tabi loads a subset of glyphs for the header. Since this (slightly) increases the initial load time, it’s a good idea to try and minimise the size of this subset, or disable it completely if you’re not using a custom font in your skin.

You can create a custom subset tailored to your site, save it as `static/custom_subset.css`, and have it load with `custom_subset = true`. Disabling the subset can be done with `enable_subset = false`.

For more information, including instructions on how to create a custom subset, see the docs.

### Full Content in Feed

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

By default, the Atom feed only contains the summary/description of your posts. You can include the entire posts’ content by setting `full_content_in_feed = true` in `config.toml`.

### Hiding Content from Feed

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

You can control how content appears in your feeds using two settings:

1. `hide_from_feed = true`: Hides content from all feeds (main, section, and tag feeds)
2. `hide_from_main_feed = true`: Hides content only from the main feed while keeping it visible in section and tag feeds

### Comments

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ❌ | ✅ | ❌ | ✅

To enable comments on an individual page, set the name of the system you want to enable to `true` in the front matter. For example, `utterances = true`.

To enable a system globally (on all pages), set `enabled_for_all_posts = true` in the correct section of your `config.toml` (e.g. inside `[extra.giscus]`).

If you have enabled a system globally, but want to disable it on a specific page, set the name of the system to `false` in the front matter of that page. For example, `utterances = false`.

Read the docs for more information on the available systems and their setup.

### iine Like Buttons

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

tabi supports iine like buttons for anonymous appreciation of your content. These privacy-focused buttons work without JavaScript and don’t track users.

To enable iine buttons globally:

    [extra]
    iine = true

You can customise the icon used for the buttons (follows the hierarchy):

    [extra]
    iine_icon = "thumbs_up"  # Options: "heart", "thumbs_up", "upvote", or any emoji

For multilingual sites, you can unify like counts across language versions of the same content (config-only setting; true by default):

    [extra]
    iine_unified_languages = true  # Likes on /es/blog/hello/ count towards /blog/hello/

You can also enable iine buttons on individual pages or sections by setting `iine = true` in their front matter, or override the icon with `iine_icon = "🚀"`.

### Analytics

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ✅

tabi supports 3 privacy-friendly analytics systems: Plausible, GoatCounter and Umami.

You can set them up in the `[extra.analytics]` section of your `config.toml`.

- `service`: Specifies which analytics service to use. Supported options are `"goatcounter"`, `"umami"`, and `"plausible"`.

- `id`: The unique identifier for your analytics service. This varies based on the service:

  - For GoatCounter, it’s the code chosen during signup. Self-hosted instances of GoatCounter don’t require this field.
  - For Umami, it’s the website ID.
  - For Plausible, it’s the domain name.

- `self_hosted_url`: Optional. Use this field to specify the URL for self-hosted instances of your chosen analytics service. The base URL differs based on your specific setup. Some examples:

  - For GoatCounter: `"https://stats.example.com"`
  - For Umami: `"https://umami.example.com"`
  - For Plausible: `"https://plausible.example.com"`

- `do_not_track`: (Umami only) Optional. When set to `true`, the generated tracking script will include the `data-do-not-track="true"` attribute, which disables tracking for users whose browsers send a “Do Not Track” header.

An example configuration for non-self-hosted GoatCounter would look like this:

    [extra.analytics]
    service = "goatcounter"
    id = "tabi"
    self_hosted_url = ""

## Footer

### Social Media Icons

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

You can add social media icons to the footer with `socials`, which takes a list of social media objects. For example:

    socials = [
        { name = "github", url = "https://github.com/welpo/", icon = "github" },
        { name = "soundcloud", url = "https://soundcloud.com/oskerwyld", icon = "soundcloud" },
        { name = "instagram", url = "https://instagram.com/oskerwyld", icon = "instagram" },
        { name = "youtube", url = "https://youtube.com/@oskerwyld", icon = "youtube" },
        { name = "spotify", url = "https://open.spotify.com/artist/5Hv2bYBhMp1lUHFri06xkE", icon = "spotify" },
    ]

To see a list of all the built-in icons, take a look at the `static/social_icons` directory on GitHub.

Missing an icon? If you think it would be a good addition to tabi, feel free to open an issue or submit a pull request (example).

To use a custom icon, you can add it to your site’s `static/social_icons` directory. For example, if you add `custom.svg`, you can reference it like this:

    { name = "custom", url = "https://example.com", icon = "custom" }

NOTE

All social links include the `rel='me'` attribute. This helps search engines and web services verify that the social media accounts are owned by you.

### Feed Icon

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

You can add a link to your RSS/Atom feed to the footer with `feed_icon = true`.

Note for Zola 0.19.X users: when there are two filenames in `feed_filenames`, only the first one will be linked in the footer.

### Footer Menu

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

You can add a menu to the footer with `footer_menu`, which takes a list of menu items. For example:

    footer_menu = [
        {url = "about", name = "about", trailing_slash = true},
        {url = "privacy", name = "privacy", trailing_slash = true},
        {url = "sitemap.xml", name = "sitemap", trailing_slash = false},
        {url = "https://example.com", name = "external link", trailing_slash = true},
    ]

### Copyright

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

To add a copyright notice to your site, set `copyright`:

    copyright = "© $CURRENT_YEAR Your Name $SEPARATOR Unless otherwise noted, the content in this website is available under the [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/) license."

You can use the following variables:

- `$TITLE` will be replaced by `title` variable set in `config.toml`
- `$CURRENT_YEAR` will be replaced by the current year
- `$AUTHOR` will be replaced by the `author` variable
- `$SEPARATOR` will be replaced by the `separator` variable

Markdown is rendered. The example above:

If you have a multilingual site and want to set different copyright notices for different languages, you can add the corresponding translation to `copyright_translations.{language_code}` for each language you want to support. The language code must match tabi’s language code. For example, for Spanish:

    copyright_translations.es = "© $CURRENT_YEAR $AUTHOR $SEPARATOR A menos que se indique lo contrario, el contenido de esta web está disponible bajo la licencia [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/)."

## Metadata

### Show author

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

To show the author(s) below the post title, set `show_author = true`.

This will display the authors set on `authors = []` in the front matter of the post. If this is not available, it will fall back to `author = ""`in `config.toml`.

### Reading Time

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

You can enable or hide the reading time of a post with `show_reading_time`. If you set it to `true`, it will be displayed in the post’s metadata, like this:

Since it follows the hierarchy, you can enable it or hide it for specific pages or sections. For example, this demo sets `show_reading_time = false` in the projects section’s `_index.md`, so their individual posts don’t show the reading time.

### Show Date

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
✅ | ✅ | ✅ | ✅ | ❌

By default, the date is shown below the post title. You can hide it with `show_date = false`. This setting follows the hierarchy.

### Date Format

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

tabi has three date formats: `long_date_format`, `short_date_format` and `archive_date_format`. The short format is used in a post’s metadata, while the long format is used when listing posts (i.e. on the blog section or the main page). The archive format is used to display day and month on the archive page.

The default is “6th July 2049” for `long_date_format` and `short_date_format` in English. For other languages, the defaut is `"%d %B %Y"` for the long format and `"%-d %b %Y"` for the short format. The universal default for the archive format is `"%d %b"`.

In Zola, time formatting syntax is inspired fom strftime. A full reference is available in the chrono docs.

#### Per-language date formats

You can customise date formats for specific languages using the `date_formats` array in `config.toml`:

    date_formats = [
        { lang = "es", long = "%d de %B de %Y", short = "%-d %b %Y", archive = "%d de %b" },
        { lang = "de", long = "%d. %B %Y", short = "%d.%m.%Y", archive = "%d. %b" },
    ]

This allows different languages to use culturally appropriate date formatting (e.g. Spanish “3 de febrero de 2024” vs German “3. Februar 2024”).

### Custom Separator

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

The separator appears in various places: in the title tag, between the metadata of a post…

The default separator is a bullet point (`•`), but you can change by setting something like `separator = "|"`.

### Title Tag Order

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

The title tag is the text that appears in the browser tab. By default, it’s the site title followed by the page title. For example, the title tag of the blog section is “~/tabi • Blog”.

By setting `invert_title_order = true`, you can invert the order of the site title and page title in the browser tab. For example, the title tag of the blog section would become “Blog • ~/tabi”.

## Security

### Encoded Email

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ✅

To protect your email address from spambots, you can encode it in the footer. You can do this by setting `email` to a base64 encoded version of your email address2. For example, `email = "bWFpbEBleGFtcGxlLmNvbQ=="` is the base64 encoded version of “mail@example.com”.

If you don’t want to encode your email yourself, tabi can encode it for you if you set `encode_plaintext_email = true`. This allows you to set a plaintext email on the config. Note that this only protects your email address on your site, not in public repositories.

If the email is encoded (either by you or by tabi), users with JavaScript disabled will not see the email icon.

### CSP (Content Security Policy)

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement to distribution of malware.

tabi has a default CSP that allows for remote images and videos, as well as YouTube and Vimeo embeds. You can customise it with `allowed_domains`, which takes a list of CSP directives. This is the default CSP:

    allowed_domains = [
        { directive = "font-src", domains = ["'self'", "data:"] },
        { directive = "img-src", domains = ["'self'", "https://*", "data:"] },
        { directive = "script-src", domains = ["'self'"] },
        { directive = "style-src", domains = ["'self'"] },
        { directive = "frame-src", domains = ["player.vimeo.com", "https://www.youtube-nocookie.com"] },
    ]

This feature is enabled by default. To disable it (and allow all connections), set `enable_csp = false` on a page, section or globally. The `enable_csp` setting follows the hierarchy.

See the CSP documentation page for more information.

## Indieweb

### Webmentions

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❓ | ❓ | ✅ | ❓ | ✅

As described by the recommended W3C standard Webmention is a simple way to notify any URL when you mention it on your site. From the receiver’s perspective, it’s a way to request notifications when other sites mention it.

For static sites webmention.io hosts a webmention endpoint that can be used to receive webmentions. This feature fetches the webmentions stored at webmention.io and displays them for a page. You will need to have setup an account for your website at webmention.io. When you enable the webmention feature it will advertise your webmention.io endpoint and display the webmentions for all posts.

Enable webmentions for your site by adding the following to your `config.toml` file.

    [extra.webmentions]
    enable = true
    # Specify the domain registered with webmention.io.
    domain = "www.example.com"

❓: To disable webmentions for a specific section or page, set `webmentions = false` in the `[extra]` section of that section or page’s front matter.

The webmentions section looks like this:

### Representative h-card

Page | Section | `config.toml` | Follows Hierarchy | Requires JavaScript
--- | --- | --- | --- | ---
❌ | ❌ | ✅ | ❌ | ❌

By default, tabi adds a hidden representative h-card to the homepage. While invisible to visitors, it’s available to microformat parsers. You can check the validity of the card with the Indiewebify.me tool.

To disable the h-card, set `enable = false` in the `[extra.hcard]` section of `config.toml`.

The default h-card includes your name, website url and social media links.

You can set a profile picture and a small bio with the `avatar` and `biography` settings.

All other h-card properties can be added by listing them under the `[extra.hcard]`section of the config file. Simply replace all `-` characters by `_`.

## Extending HTML Elements in tabi

Some HTML elements in tabi can be extended to support additional use cases such as adding custom JavaScript for site-wide behavior at the end of the `<body>` tag or including additional content at the end of the `<head>` element that is not otherwise supported by other tabi settings.

See the table below for elements that can be extended:

Element | Template
--- | ---
`<head>` | `templates/tabi/extend_head.html`
`<body>` | `templates/tabi/extend_body.html`

There are no explicit settings to configure for your site or pages. Simply create the relevant template file for your site, and tabi will automatically include it.

1. If you’re using a remote Git repository, you might want to automate the process of updating the `updated` field. Here’s a guide for that: Zola Git Pre-Commit Hook: Updating Post Dates. ↩

2. To encode your email in base64 you can use online tools or, on your terminal, run: `printf 'mail@example.com' | base64`. ↩
