    Minify URI

    -

    Place this URI in your HTML to serve the files above combined, minified, compressed and -with cache headers.

    - - - -
    URI/min (opens in new window)
    HTML
    - -

    How to serve these files as a group

    -

    For the best performance you can serve these files as a pre-defined group with a URI -like: /min/?g=keyName

    -

    To do this, add a line like this to /min/groupsConfig.php:

    - -
    return array(
-	... your existing groups here ...
-
-);
    - -

    Make sure to replace keyName with a unique key for this group.

    -
    - -
    -

    Find URIs on a Page

    -

    You can use the bookmarklet below to fetch all CSS & Javascript URIs from a page -on your site. When you active it, this page will open in a new window with a list of -available URIs to add.

    - -

    Create Minify URIs (right-click, add to bookmarks)

    -
    - -

    Combining CSS files that contain @import

    -

    If your CSS files contain @import declarations, Minify will not -remove them. Therefore, you will want to remove those that point to files already -in your list, and move any others to the top of the first file in your list -(imports below any styles will be ignored by browsers as invalid).

    -

    If you desire, you can use Minify URIs in imports and they will not be touched -by Minify. E.g. @import "/min/?g=css2";
