This was created due to the previous minifier (jekyll-press) not being CSS3 compatible, which made me frown.
Note: this is my first ever gem, I'm learning, so feedback is much appreciated.
Easy to use, just install the jekyll-minifier gem:
gem install jekyll-minifier
Then add this to your _config.yml:
gems: - jekyll-minifier
Optionally, you can also add exclusions using:
jekyll-minifier: exclude: 'atom.xml' # Exclude files from processing - file name, glob pattern or array of file names and glob patterns
