# Images
|
||
|
||
While images are first-class citizens of Markdown and part of the core syntax,
|
||
it can be difficult to work with them. Material for MkDocs makes working with
|
||
images more comfortable by providing styles for alignment and image captions.

||
## Configuration
|
||
|
||
### Attribute List
|
||
|
||
The [Attribute List][2] extension, which is part of the standard Markdown
|
||
library, allows to __add HTML attributes and CSS classes to Markdown elements__,
|
||
and can be enabled via `mkdocs.yml`
|
||
|
||
``` yaml
|
||
markdown_extensions:
|
||
- attr_list
|
||
```
|
||
|
||

|
||
|
||
## Usage
|
||
|
||
### Image alignment
|
||
|
||
When the [Attribute List][3] extension is enabled, images can be aligned by
|
||
adding the respective alignment directions via the `align` attribute, i.e.
|
||
`align=left` or `align=right`
|
||
|
||
=== "Left"
|
||
|
||
_Example_:
|
||
|
||
``` markdown
|
||
{: align=left }
|
||
```
|
||
|
||
_Result_:
|
||
|
||
{: align=left width=300 }
|
||
|
||
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
|
||
nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
|
||
massa, nec semper lorem quam in massa.
|
||
|
||
=== "Right"
|
||
|
||
_Example_:
|
||
|
||
``` markdown
|
||
{: align=right }
|
||
```
|
||
|
||
_Result_:
|
||
|
||
{: align=right width=300 }
|
||
|
||
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
|
||
nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
|
||
massa, nec semper lorem quam in massa.
|
||
|
||
_If there's insufficient space to render the text next to the image, the image
|
||
will stretch to the full width of the viewport, e.g. on mobile viewports._

||

|
||
|
||
### Image captions
|
||
|
||
Sadly, the Markdown syntax doesn't provide native support for image captions,
|
||
but it's always possible to resort to HTML. Using `figure` and `figcaption`, captions can be added to images.
|
||
|
||
_Example_:
|
||
|
||
```html
|
||
<figure>
|
||
<img src="https://dummyimage.com/600x400/eee/aaa" width="300" />
|
||
<figcaption>Image caption</figcaption>
|
||
</figure>
|
||
```
|
||
|
||
_Result_:
|
||
<figure>
|
||
<img src="https://dummyimage.com/600x400/f5f5f5/aaaaaa&text=–%20Image%20–" width="300" />
|
||
<figcaption>Image caption</figcaption>
|
||
</figure>
|
||
|
||
### Image lazy-loading
|
||
|
||
Modern browsers provide [native support for lazy-loading images][4] through the
|
||
`loading` attribute, which degrades to eager-loading in browsers without
|
||
support. As with [image alignment][5], if the [Attribute List][3] extension is
|
||
enabled, images can be lazy-loaded by adding `loading=lazy`.
|
||
|
||
_Example_:
|
||
|
||
``` markdown
|
||
{: loading=lazy }
|
||
```
|
||
|
||
_Result_:
|
||
|
||
{: loading=lazy width=300 }
