# 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],

The awesome thing about social cards is that they are generated during
build time and directly distributed with your documentation, no external
services involved. While it would technically be simpler to generate
social cards using a web browser and an automation framework like
[Puppeteer], it would add further liabilities to the toolchain, with the
potential to make build pipelines more complex and resource intense.
For this reason, Material for MkDocs again follows its core principle of
making it as simple and powerful as possible, providing an easy-to-use
framework for building [custom layouts] using Python image processing
libraries. Additionally, this means that there's no necessity for internet
access in CI environments.

Default: `default` Layout specification the social card should use. The
plugin includes the following layouts which make use of the [color palette]
and [font]:
Two Python libraries must be installed alongside Material for MkDocs to generate
the social preview images, both of which are based on [Cairo Graphics]
[Pillow] and [CairoSVG]:
=== "`default`"
```
pip install pillow cairosvg
```
``` yaml
plugins:
- social:
cards_layout: default
```
Both libraries are built with native extensions which need to be installed as
well. The [Docker image] comes with all dependencies pre-installed. If you don't
want to use Docker, see the following section which explains how to install all
dependencies on your system:
This layout uses the configured [primary color] as a background:
=== ":material-apple: macOS"
[![Layout default]][Layout default]
Make sure [Homebrew] is installed, which is a modern package manager for
macOS. Next, use the following command to install all necessary
dependencies:
=== "`default/variant`"
```
brew install cairo freetype libffi libjpeg libpng zlib
``` yaml
plugins:
- social:
cards_layout: default/variant
```
This layout includes the [page icon] as a watermark, if defined:
[![Layout default variant]][Layout default variant]
=== "`default/accent`"
``` yaml
plugins:
- social:
cards_layout: default/accent
```
This layout uses the configured [accent color] as a background:
[![Layout default accent]][Layout default accent]
=== "`default/invert`"
``` yaml
plugins:
- social:
cards_layout: default/invert
```
This layout inverts the background and foreground colors:
[![Layout default invert]][Layout default invert]
All of the `default` layouts use the following variables:
- :material-page-layout-header: `config.site_name`
- :material-page-layout-body: `page.meta.title` or `page.title`
- :material-page-layout-footer: `page.meta.description` or `config.site_description`
- :material-page-layout-sidebar-right: `theme.logo` or `theme.icon.logo`
[`cards_layout_params`](#+social.cards_layout_params){ #+social.cards_layout_params }
: [:octicons-tag-24: insiders-4.33.0][Insiders] · :octicons-milestone-24:
Default: _none_ This option allows to set [parameters] as provided by
the layout specification. For [custom layouts], this key can be used to
provide layout-specific options, making layouts entirels configurable.
---
All [`default`][default layouts] layouts specify the following parameters:
[`background_color`](#+social.cards_layout_params.background_color){ #+social.cards_layout_params.background_color }
: Set a background color, which can be a [CSS color keyword], a 3, 4, 6
or 8 letter HEX color code. Alpha channels are supported as well:
``` yaml
plugins:
- social:
cards_layout_params:
background_color: "#0FF1CE"
```
[`background_image`](#+social.cards_layout_params.background_image){ #+social.cards_layout_params.background_image }
: Set a background image. If a `background_color` is set, like for the
[`default`][default layouts] layouts, the image is tinted (overlayed)
with the color. Thus, the background color must be (partially)
transparent for the image to become visible:
``` yaml
plugins:
- social:
cards_layout_params:
background_color: "#00000000"
background_image: .overrides/social/background.png
```
The path of the image must be defined relative to the project root.
[`color`](#+social.cards_layout_params.color){ #+social.cards_layout_params.color }
: Set a foreground color, which can be a [CSS color keyword], a 3, 4, 6
or 8 letter HEX color code. The color is primarily used to tint text and
icons:
``` yaml
plugins:
- social:
cards_layout_params:
color: "#0FF1CE"
```
[`font_family`](#+social.cards_layout_params.font_family){ #+social.cards_layout_params.font_family }
: Set a font family. This overrides the [font] that is set as part of the
theme configuration. The [built-in social plugin] will automatically
download the font from [Google Fonts]:
``` yaml
plugins:
- social:

#### Caching
The [built-in social plugin] implements an intelligent caching mechanism,
ensuring that social cards are only re-generated when they're not contained in
the cache or their contents change. If any of the variables used in a layout
changes, the plugin will detect it and re-generate the card.
The following configuration options are available for caching:
[`cache`](#+social.cache){ #+social.cache }
: [:octicons-tag-24: insiders-4.33.0][Insiders] · :octicons-milestone-24:
Default: `true` Whether the plugin queries its cache for an existing
artifact before starting a generation job. It's normally not necessary to
change this setting, except for when debugging the plugin itself. Caching
can be disabled with:
``` yaml
plugins:
- social:
cache: false
```
=== ":fontawesome-brands-windows: Windows"
[`cache_dir`](#+social.cache_dir){ #+social.cache_dir }
As stated in the [installation guide], the easiest way to get up and running
with the [Cairo Graphics] library on Windows is by installing [GTK+], since
it has Cairo as a dependency. You can also download and install a
precompiled [GTK runtime].
: :octicons-milestone-24: Default: `.cache/plugins/social` This option
specifies the file system location of the plugin's cache. It's normally not
necessary to change this setting, except for when debugging the plugin
itself. The cache directory can be changed with:
=== ":material-linux: Linux"
There are several package managers for Linux with varying availability per
distribution. The [installation guide] explains how to install the [Cairo
Graphics] library for your distribution:
=== ":material-ubuntu: Ubuntu"
```
apt-get install libcairo2-dev libfreetype6-dev libffi-dev libjpeg-dev libpng-dev libz-dev
```
=== ":material-fedora: Fedora"
```
yum install cairo-devel freetype-devel libffi-devel libjpeg-devel libpng-devel zlib-devel
```
=== ":fontawesome-brands-suse: openSUSE"

#### Caching <small>recommended</small> { #caching data-toc-label="Caching" }
The [built-in social plugin] 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], add the following lines:
``` yaml hl_lines="15-20"
name: ci
on:
push:
branches:
- master
- main
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- uses: actions/setup-python@v4
with:
python-version: 3.x
- uses: actions/cache@v3
with:
key: mkdocs-material-${{ github.sha }}
path: .cache
restore-keys: |
mkdocs-material-
- run: pip install mkdocs-material
- run: mkdocs gh-deploy --force
``` yaml
plugins:
- social:
cache_dir: .cache/plugins/social
```
By default, all built-in plugins that implement caching will create a
`.cache` directory in the same folder your `mkdocs.yml` resides, and create
subfolders to not interfere with each other. If you use multiple instances
of this plugin, it could be necessary to change this setting.

[publishing guide]: ../publishing-your-site.md#with-github-actions
#### Meta tags
The [built-in social plugin] automatically sets all necessary `meta` tags,
equivalent to the following two customizations, which you can set manually when
you don't want to use it:
=== ":material-graph: Open Graph"
``` html
{% extends "base.html" %}
{% block extrahead %}
{% set title = config.site_name %}
{% if page and page.meta and page.meta.title %}

### Choosing a font
Some fonts do not contain CJK characters, like for example the
[default font, `Roboto`][font]. In case your `site_name`, `site_description`, or
page title contain CJK characters, choose another font from [Google Fonts] which
comes with CJK characters, e.g. one from the `Noto Sans` font family:
