### 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`.

```
_Result_:
![Placeholder](https://dummyimage.com/600x400/f5f5f5/aaaaaa&text=%20Image%20){: loading=lazy width=300 }
