Summary

The CSS background-image property sets one or several background images for an element. The images are drawn on stacking context layers on top of each other. The first layer specified is drawn as if it is closest to the user.

The borders of the element are then drawn on top of them, and the background-color is drawn beneath them. How the images are drawn relative to the box and its borders is defined by the background-clip and background-origin CSS properties.

If a specified image cannot be drawn (for example, when the file denoted by the specified URI cannot be loaded), browsers handle it as they would a none value.

Note: Even if the images are opaque and the color won't be displayed in normal circumstances, web developers should always specify a background-color. If the images cannot be loaded—for instance, when the network is down—the background color will be used as a fallback.

Syntax

background-image: none;
background-image: url(http://www.example.com/bck.png);

background-image: inherit;

Values

none
Is a keyword denoting the absence of images.
<image>
Is an <image> denoting the image to display. There can be several of them, separated by commas, as multiple backgrounds are supported.

Formal syntax

<bg-image>#

where
<bg-image> = none | <image>
