The background-origin
CSS property sets the background's origin: from the border start, inside the border, or inside the padding.
Note that background-origin
is ignored when background-attachment
is fixed
.

Examples
Setting background origins
.example { border: 10px double; padding: 10px; background: url("image.jpg"); background-position: center left; background-origin: content-box; }
#example2 { border: 4px solid black; padding: 10px; background: url("image.gif"); background-repeat: no-repeat; background-origin: border-box; }
div { background-image: url("logo.jpg"), url("mainback.png"); /* Applies two images to the background */ background-position: top right, 0px 0px; background-origin: content-box, padding-box; }
Using two gradients
In this example the box has a thick dotted border. The first gradient uses the padding-box
as the background-origin
and therefore the background sits inside the border. The second uses the content-box
and so only displays behind the content.
.box { margin: 10px 0; color: #fff; background: linear-gradient( 90deg, rgba(131, 58, 180, 1) 0%, rgba(253, 29, 29, 0.6) 60%, rgba(252, 176, 69, 1) 100% ), radial-gradient(circle, rgba(255, 255, 255, 1) 0%, rgba(0, 0, 0, 1) 28%); border: 20px dashed black; padding: 20px; width: 400px; background-origin: padding-box, content-box; background-repeat: no-repeat; }
<div class="box">Hello!</div>
