What does this do?
This CMSMS cssMinifier plugin lets a user convert the default {cms_stylesheet} into a minified css file.
This function takes a css-string and compresses it, removing unneccessary whitespace, colons, removing unneccessary px/em declarations etc.
How do I use it?
Upload the plugin file into your assets\plugins folder first. Insert the tag {cssMinifier} into the "head" section of your template (case sensitive) this way:
