The CSS background-image
property sets one or several background images for an element.
background-image: none; background-image: url('http://www.example.com/bck.png'); background-image: inherit;
The background 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.
background-color
. If the images cannot be loaded—for instance, when the network is down—the background color will be used as a fallback.Initial value | none |
---|---|
Applies to | all elements. It also applies to ::first-letter and ::first-line . |
Inherited | no |
Media | visual |
Computed value | as specified, but with url values made absolute |
Animation type | discrete |
Canonical order | the unique non-ambiguous order defined by the formal grammar |
Syntax
Each background image is specified either as the keyword none
or as an <image>
value.
To specify multiple background images, supply multiple values, separated by a comma:
background-image: linear-gradient(to bottom, rgba(255,255,0,0.5), rgba(0,0,255,0.5)), url('https://mdn.mozillademos.org/files/7693/catfront.png');
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.

Examples
Note that the star image is partially transparent and is layered over the cat image.
