<h2 id="Summary">Summary</h2>

<p>The <strong><code>@import</code></strong> <a href="/en/CSS" title="CSS">CSS</a> <a href="/en/CSS/At-rule" title="At-rule">at-rule</a>&nbsp;is used to import style rules from other style sheets. These rules must precede all other types of rules, except {{ cssxref("@charset") }} rules; as it is not a <a href="/en/CSS/Syntax#nested_statements" title="en/CSS/Syntax#nested_statements">nested statement</a>, it cannot be used inside <a href="/en/CSS/At-rule#Conditional_Group_Rules" title="en/CSS/At-rule#Conditional_Group_Rules">conditional group at-rules</a>.</p>

<p>So that user agents can avoid retrieving resources for unsupported media types, authors may specify media-dependent <code>@import</code> rules. These conditional imports specify comma-separated <a href="/en/CSS/Media_queries" title="Using CSS media queries">media queries</a> after the URI. In the absence of any media query, the import is unconditional. Specifying <code>all</code> for the medium has the same effect.</p>

 <dt style="margin: 0 40px"><em>url</em></dt>
 <dd style="margin: 0 40px">Is a {{ xref_cssstring() }} or a {{ xref_cssuri() }} 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. <strong>chrome://communicator/skin/</strong>). <a href="/en-US/docs/XUL/Tutorial/The_Chrome_URL" title="/en-US/docs/XUL/Tutorial/The_Chrome_URL">See here</a> for more information.</dd>
 <dt style="margin: 0 40px"><em>list-of-media-queries</em></dt>
 <dd style="margin: 0 40px">Is a comma-separated list of <a href="/en/CSS/Using_CSS_media_queries" rel="internal" title="en/CSS/Using_CSS_media_queries">media queries</a> 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.</dd>
