CSS background Property


Set different background properties in one declaration:

body {
    background: #00ff00 url("smiley.gif") no-repeat fixed center;
Try it Yourself »

Definition and Usage

The background shorthand property sets all the background properties in one declaration.

The properties that can be set, are: background-color, background-image, background-position, background-size, background-repeat, background-origin, background-clip, and background-attachment.

It does not matter if one of the values above are missing, e.g. background:#ff0000 url(smiley.gif); is allowed.

Default value: see individual properties
Inherited: no
Animatable: yes, see individual properties. Read about animatable Try it
Version: CSS1 + new properties in CSS3
JavaScript syntax:"red url(smiley.gif) top left no-repeat" Try it

Browser Support

The numbers in the table specify the first browser version that fully supports the property.

background 1.0 4.0 1.0 1.0 3.5

Note: Internet Explorer 8 and earlier versions do not support multiple background images on one element.

Note: See individual browser support for each value below.

CSS Syntax

background: bg-color bg-image position/bg-size bg-repeat bg-origin bg-clip bg-attachment initial|inherit;

Note: If one of the properties in the shorthand declaration is the bg-size property, you must use a / (slash) to separate it from the bg-position property, e.g. background:url(smiley.gif) 10px 20px/50px 50px; will result in a background image, positioned 10 pixels from the left, 20 pixels from the top, and the size of the image will be 50 pixels wide and 50 pixels high.

Note: If using multiple background-image sources but also want a background-color, the background-color parameter needs to be last in the list.
