import property CSS Reference

Definition and Usage

The @import CSS at-rule allows to import style rules from other style sheets. These rules must precede all other types of rules, except @charset rules; as it is not a nested statement, it cannot be used inside conditional group at-rules.

So that user agents can avoid retrieving resources for unsupported media types, authors may specify media-dependent @import rules. These conditional imports specify comma-separated media queries after the URI. In the absence of any media query, the import is unconditional. Specifying all for the medium has the same effect.


@import url;
@import url list-of-media-queries;

where :

Is a <string> or a <uri> representing the location of the resource to import. The url may be an absolute or relative url. Note that the url needn't actually specify a file; it can just specify the package name and part, and the appropriate file will be chosen automatically (eg. chrome://communicator/skin/).
Is a comma-separated list of media queries conditioning the application of the css rules defined in the linked url. If the browser doesn't support any of these media types, it won't even load the linked resource.


@import url("fineprint.css") print;
@import url("bluish.css") projection, tv;
@import 'custom.css';
@import url("chrome://communicator/skin/");
@import "common.css" screen, projection;
@import url('landscape.css') screen and (orientation:landscape);
