New description:

 I use some extrenal js lib assets in the my django project (automatically
 installed by the bower js package manager).

 Some css source code has {{{url()}}} statement inside the comment {{{/*
 */}}} with wrong relatative path to img/font.

 During running command {{{python manage.py collectstatic}}} I get error
 message.

 whitenoise.storage.MissingFileError: The file 'colorPicker/_blank.gif'

 The CSS file 'colorPicker/index.css' references a file which could not be
 found:
   colorPicker/_blank.gif

 Please check the URL references in this CSS file, particularly any
 relative paths which might be pointing to the wrong location.
 }}}

 {{{ url('_blank.gif') }}} statement is inside comment in the css source
 code.

 Problem is that {{{@import}}} rule and {{{url()}}} statement are checked
 in all css file source code content, include code between css comment
 {{{/* */}}}.
 ( regex pattern for the match rule/statement {{{
 django.contrib.staticfiles.storage.HashedFilesMixin.patterns}}})

 I write patch which match this rule and statement only outside of the css
 comment in css file source code.
