["Felix Scheffer (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TAP5-1377?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Felix Scheffer updated TAP5-1377:
---------------------------------
    Attachment: 0002-TAP5-1377-Combine-CSS-files-in-production-mode.patch

Some basic support for combing css files but not 100% of what the OP asked for in the description:

* No unpacking of @import statements. Requires parsing the css file (=lots of extra work). 
* The file name of the original file is not added to the combined file (We dont do that when combining js files)
* There is no support for "nocombine"
* Stacks with conditional style sheets are not combined. (One css file per condition would be required)

> When in production mode, combine CSS files into a single file as is done with javascript resources. 
>  * Any relative references to urls in the CSS contents should be absolutized based on the URL of the original CSS path so that things like background images continue to function. 
>  * @import statements should also be unpacked so that designers have flexibility in how the files are structured. 
>  * Any CSS files that have a class on the link element of "nocombine" or that have a non default/non-screen media should not be combined.
>  * Record a comment before each file saying which CSS file it originally came from
