The CSS @import @-rule allows users to import style rules from other style sheets. 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 types after the URI. In the absence of any media types, the import is unconditional. Specifying all for the medium has the same effect.

CSS example:

@import url("fineprint.css") print;
@import url("bluish.css") projection, tv;
