# Setting up social cards
|
||
|
||
Social cards, also known as social previews, are images that are displayed when
|
||
a link to your project documentation is shared on social media. Material for
|
||
MkDocs can generate beautiful social cards automatically, using the [colors][1],
|
||
[fonts][2] and [logo][3][^1] defined in `mkdocs.yml`.
|
||
|
||
[^1]:
|
||
Both types of logos, images (`theme.logo`) and icons (`theme.icon.logo`)
|
||
are supported. While an image logo is used as-is, icons are filled with the
|
||
color used in the header (white or black), which depends on the primary
|
||
color.

## Configuration
|
||
|
||
### Built-in social cards
|
||
|
||
[:octicons-heart-fill-24:{ .mdx-heart } Insiders][Insiders]{ .mdx-insiders } ·
|
||
:octicons-cpu-24: Plugin ·
|
||
:octicons-beaker-24: Experimental ·
|
||
[:octicons-tag-24: insiders-2.12.0][Insiders]
|
||
|
||
The [built-in social cards plugin][4] generates a social card image for every
|
||
page and adds the necessary meta tags, so it's displayed on social media when
|
||
shared. Enable it via `mkdocs.yml`:
|
||
|
||
``` yaml
|
||
plugins:
|
||
- social
|
||
```
|
||
|
||
For example, the page on [setting up site analytics][5] renders as:
|
||
|
||
<figure markdown>
|
||
|
||
[![Social Cards][6]][6]
|
||
|
||
<figcaption markdown>
|
||
|
||
Want to try it out? Copy the current URL and paste it into [Twitter's Card
|
||
validator][7] to see how social cards look in action.
|
||
|
||
</figcaption>
|
||
</figure>
|
||
|
||
This is a built-in plugin, which means that no third-party plugin needs to be
|
||
installed, as Material for MkDocs already bundles it. The following options
|
||
are available:
|
||
|
||
`cards_color`{ #cards-color } :material-new-box:
|
||
|
||
: :octicons-milestone-24: Default: [`primary
|
||
color`][8]_ – This option specifies which colors to use for the background
|
||
`fill` and foreground `text` when generating the social card.
|
||
|
||
``` yaml
|
||
plugins:
|
||
- social:
|
||
cards_color:
|
||
fill: "#0FF1CE"
|
||
text: "#FFFFFF"
|
||
```
|
||
|
||
Note that the values for `fill` and `text` can either be HEX color values
|
||
(e.g. `#0FF1CE`, must be enclosed in quotes) or CSS color keywords (e.g.
|
||
`red`, `green`, etc.).
|
||
|
||
`cards_directory`{ #cards-directory }
|
||
|
||
: :octicons-milestone-24: Default: `assets/images/social` – This option
|
||
specifies where the generated social card images will be written to. It
|
||
should normally not be necessary to change this option.
|
||
|
||
``` yaml
|
||
plugins:
|
||
- social:
|
||
cards_directory: assets/images/social
|
||
```

|
||
|
||
#### Caching
|
||
|
||
When enabled, the [social cards plugin][9] automatically fetches the fonts you
|
||
define in `mkdocs.yml` from Google Fonts, and uses them to render the text that
|
||
is displayed on the social card. The font files and generated cards are both
|
||
written to the `.cache` directory, which is used in subsequent builds to detect
|
||
whether the social cards need to be regenerated. You might want to:
|
||
|
||
1. Ignore the `.cache` directory in your project, by adding it to `.gitignore`.
|
||
2. When building your site for publishing, use a build cache to save the
|
||
`.cache` directory in between builds. Taking the example from the
|
||
[publishing guide][10], add the following lines:
|
||
|
||
``` yaml hl_lines="15-18"
|
||
name: ci
|
||
on:
|
||
push:
|
||
branches:
|
||
- master
|
||
- main
|
||
jobs:
|
||
deploy:
|
||
runs-on: ubuntu-latest
|
||
steps:
|
||
- uses: actions/checkout@v2
|
||
- uses: actions/setup-python@v2
|
||
with:
|
||
python-version: 3.x
|
||
- uses: actions/cache@v2
|
||
with:
|
||
key: ${{ github.ref }}
|
||
path: .cache
|
||
- run: pip install mkdocs-material
|
||
- run: mkdocs gh-deploy --force
|
||
```

|

|
||
|
||
## Usage
|
||
|
||
If you want to adjust the title or set a custom description for the social card,
|
||
you can use the [Metadata][11] extension, which takes precedence over the
|
||
default values.
|
||
|
||
- [Changing the title][12]
|
||
- [Changing the description][13]

||

|
||
[12]: ../reference/meta-tags.md#setting-the-page-title
|
||
[13]: ../reference/meta-tags.md#setting-the-page-description
|
||
|
||
### Using social media meta tags
|
||
|
||
The [built-in social cards plugin] generates beautiful image previews for social
|
||
media during the build and sets all necessary `meta` tags, equivalent to the
|
||
following two customizations:
|
||
|
||
=== ":material-graph: Open Graph"
|
||
|
||
``` html
|
||
{% block extrahead %}
|
||
{% set title = config.site_name %}
|
||
{% if page and page.meta and page.meta.title %}
|
||
{% set title = title ~ " - " ~ page.meta.title %}
|
||
{% elif page and page.title and not page.is_homepage %}
|
||
{% set title = title ~ " - " ~ page.title | striptags %}
|
||
{% endif %}
|
||
<meta property="og:type" content="website" />
|
||
<meta property="og:title" content="{{ title }}" />
|
||
<meta property="og:description" content="{{ config.site_description }}" />
|
||
<meta property="og:url" content="{{ page.canonical_url }}" />
|
||
<meta property="og:image" content="<url>" />
|
||
<meta property="og:image:type" content="image/png" />
|
||
<meta property="og:image:width" content="1200" />
|
||
<meta property="og:image:height" content="630" />
|
||
{% endblock %}
|
||
```
|
||
|
||
=== ":fontawesome-brands-twitter: Twitter Cards"
|
||
|
||
``` html
|
||
{% block extrahead %}
|
||
{% set title = config.site_name %}
|
||
{% if page and page.meta and page.meta.title %}
|
||
{% set title = title ~ " - " ~ page.meta.title %}
|
||
{% elif page and page.title and not page.is_homepage %}
|
||
{% set title = title ~ " - " ~ page.title | striptags %}
|
||
{% endif %}
|
||
<meta name="twitter:card" content="summary_large_image" />
|
||
<meta name="twitter:site" content="<username>" />
|
||
<meta name="twitter:creator" content="<username>" />
|
||
<meta name="twitter:title" content="{{ title }}" />
|
||
<meta name="twitter:description" content="{{ config.site_description }}" />
|
||
<meta name="twitter:image" content="<url>" />
|
