00080 <h2>How to serve these files as a group</h2>
00081 <p>For the best performance you can serve these files as a pre-defined group with a URI
00082 like: <code><span class=minRoot>/min/?</span>g=keyName</code></p>
00083 <p>To do this, add a line like this to /min/groupsConfig.php:</p>
00084
00085 <pre><code>return array(
00086     <span style="color:#666">... your existing groups here ...</span>
00087 <input id=groupConfig size=100 type=text readonly>
00088 );</code></pre>
00089
00090 <p><em>Make sure to replace <code>keyName</code> with a unique key for this group.</em></p>

00095 <p>You can use the bookmarklet below to fetch all CSS &amp; Javascript URIs from a page
00096 on your site. When you active it, this page will open in a new window with a list of
00097 available URIs to add.</p>

00101
00102 <h3>Combining CSS files that contain <code>@import</code></h3>
00103 <p>If your CSS files contain <code>@import</code> declarations, Minify will not
00104 remove them. Therefore, you will want to remove those that point to files already
00105 in your list, and move any others to the top of the first file in your list
00106 (imports below any styles will be ignored by browsers as invalid).</p>
00107 <p>If you desire, you can use Minify URIs in imports and they will not be touched
00108 by Minify. E.g. <code>@import "<span class=minRoot>/min/?</span>g=css2";</code></p>
