The |compacte filter is applied to a CSS or JavaScript file [1] and creates a compressed copy which is smaller than the original as it deletes all comments, empty declarations, unnecessary blank spaces and lines etc. [2] (for Javascript files, the filter uses the JavaScriptPacker class).
Ater having archived this new file into the local/ directory, the filter returns the link: [<link rel="stylesheet" href="(#CHEMIN{spip_style.css}|compacte)" type="text/css" media="all" />] which will return something like: <link rel="stylesheet" href="local/cache-css/spip_style-compacte-092e.css" type="text/css" media="all" />
À noter
This filter, like automatic compression, groups together css files compressed by media.
Example :
[<link rel="stylesheet" href="(#CHEMIN{spip_style.css}|compacte)" type="text/css" media="all" />]
[<link rel="stylesheet" href="(#CHEMIN{habillage.css}|compacte)" type="text/css" media="all" />]
[<link rel="stylesheet" href="(#CHEMIN{responsive.css}|compacte)" type="text/css" media="handheld" />]
[<link rel="stylesheet" href="(#CHEMIN{print.css}|compacte)" type="text/css" media="print" />]
The spip_styles.css and habillage.css stylesheets will be grouped together in the same compressed file. responsive.css and print.css will be in separate compressed files with the media="handheld" and media="print" attributes respectively.

For css files, you need to enter one of the following attributes in your tag <link> :
