# Lazy loading images in HTML
|
|
|
|
To implement [[Lazy Loading]] to an `<img ... >` tag, add the attrbitue `loading=lazy`
|
|
|
|
<img loading=lazy ... >
|
|
|
|
This will load the image when scrolling is near the viewport, using the [Intersection Observer API](https://developers.google.com/web/updates/2016/04/intersectionobserver)
