CSS @import Rule


Example

Import the "navigation.css" style sheet into the current style sheet:

@import "navigation.css"; /* Using a string */

or

@import url("navigation.css"); /* Using a url */

More examples below.


Definition and Usage

The @import rule allows you to import a style sheet into another style sheet.

The @import rule must be at the top of the document (but after any @charset declaration).

The @import rule also supports media queries, so you can allow the import to be media-dependent.
