Does not support CSS3 syntax

[wei2912]

The plugin is unable to parse some CSS3 syntax.

For example, look at https://github.com/linuxtuts/linuxtuts.github.com

parse error occurred while processing: /_site/css/colors/transparent.css
details: parse error on value "$" ($end)
copying initial file
parse error occurred while processing: /_site/css/depend/fixstyles.css
details: parse error on value ":not(" (error)
copying initial file
parse error occurred while processing: /_site/css/mqs/print.css
details: parse error on value "^=" (error)
copying initial file
Successfully generated site: linuxtuts.github.com -> linuxtuts.github.com/_site

Is there a git repo (or zip) where this bug can be reproduced?

Yes, github.com/linuxtuts/linuxtuts.github.com

I'm getting following:

parse error occurred while processing: /_site/css/colors/transparent.css
details: parse error on value "$" ($end)
copying initial file
parse error occurred while processing: /_site/css/depend/fixstyles.css
details: parse error on value ":not(" (error)
copying initial file
parse error occurred while processing: /_site/css/mqs/print.css
details: parse error on value "^=" (error)
copying initial file
Successfully generated site: linuxtuts.github.com -> linuxtuts.github.com/_site

So jekyll-press processing all files, but css_press can't minify them beacuse there is parse errors. Parse errors are caused beacause csspool doesn't support all css3 syntax. See issue tracker

I'm thinking about make it possible to use other css minifiers.

Oh, so that's why... and yes, my site uses CSS3 syntax.

I added ability to swap css minifier (see my new gem multi_css). To use other css minifier simply add it to Gemfile. Try for example gem "cssminify"
