# Tooltips

Material for MkDocs makes it trivial to add tooltips to links, abbreviations
and all other elements, which allows for implementing glossary-like
functionality, as well as small hints that are shown when the user hovers or 
focuses an element.

## Configuration

This configuration enables support for tooltips and abbreviations and allows to 
build a simple glossary, sourcing definitions from a central location. Add the 
following lines to `mkdocs.yml`:

``` yaml
markdown_extensions:
  - abbr
  - attr_list
  - pymdownx.snippets
```

See additional configuration options:

- [Abbreviations]
- [Attribute Lists]
- [Snippets]

  [Abbreviations]: ../setup/extensions/python-markdown.md#abbreviations
  [Attribute Lists]: ../setup/extensions/python-markdown.md#attribute-lists
  [Snippets]: ../setup/extensions/python-markdown-extensions.md#snippets

### Improved tooltips

[:octicons-heart-fill-24:{ .mdx-heart } Sponsors only][Insiders]{ .mdx-insiders } ·
[:octicons-tag-24: insiders-4.15.0][Insiders] ·
:octicons-beaker-24: Experimental

When improved tooltips are enabled, Material for MkDocs replaces the browser's
rendering logic for `title` attribute with beautiful little tooltips.
Add the following lines to `mkdocs.yml`:

``` yaml
theme:
  features:
    - content.tooltips
```

Now, tooltips will be rendered for the following elements:

- __Content__ – elements with a `title`, permalinks and copy-to-clipboard button
- __Header__ – home button, header title, color palette switch and repository link
- __Navigation__ – links that are shortened with ellipsis, i.e. `...`

## Usage

### Adding tooltips

The [Markdown syntax] allows to specify a `title` for each link, which will
render as a beautiful tooltip when [improved tooltips] are enabled. Add a 
tooltip to a link with the following lines:

``` markdown title="Link with tooltip, inline syntax"
[Hover me](https://example.com "I'm a tooltip!")
```

<div class="result" markdown>

[Hover me](https://example.com "I'm a tooltip!")

</div>

Tooltips can also be added to link references:

``` markdown title="Link with tooltip, reference syntax"
[Hover me][example]

  [example]: https://example.com "I'm a tooltip!"
```

<div class="result" markdown>

[Hover me](https://example.com "I'm a tooltip!")

</div>

For all other elements, a `title` can be added by using the [Attribute Lists]
extension:

``` markdown title="Icon with tooltip"
:material-information-outline:{ title="Important information" }
```

<div class="result" markdown>

:material-information-outline:{ title="Important information" }

</div>

### Adding abbreviations

Abbreviations can be defined by using a special syntax similar to [links] and 
[footnotes], starting with a `*` and immediately followed by the term or
acronym to be associated in square brackets:

``` markdown title="Text with abbreviations"

### Adding a glossary

The [Snippets] extension can be used to implement a simple glossary by moving
all abbreviations in a dedicated file[^1], and embedding it with the
[`--8<--` notation][Snippets notation] at the end of each document:

  [^1]:
    It's highly recommended to put the Markdown file containing the
    abbreviations outside of the `docs` folder (here, a folder with the name 
    `includes` is used), as MkDocs might otherwise complain about an
    unreferenced file.

=== ":octicons-file-code-16: docs/example.md"

    ```` markdown
    The HTML specification is maintained by the W3C.

    --8<-- "includes/abbreviations.md"
    ````

=== ":octicons-file-code-16: includes/abbreviations.md"

    ```` markdown
    *[HTML]: Hyper Text Markup Language
    *[W3C]: World Wide Web Consortium
    ````
