Until recently I was using Chirpy VS plugin for mashing css files. But I have found it doesn't change css url relative paths during mashing and it is a problem for me now (as I mash css files which access local images but are placed in different directories).
Is there any tool which mashes css files and changes urls relative paths accordingly?
I have found this workitem which proves there is a bug in Chirpy.
Also it looks like CrusherModule will solve my problem.
Update. Finally I used CrushIt
