How many times have you wished to minify in a clean way all the stylesheets and scripts of a WordPress website?
AssetsMinify takes every CSS and JS asset included using wp_enqueue_style() and wp_enqueue_script(), merges and minifies them.
You can also use AssetsMinify to create your WP theme using Compass / Sass / Less without configuring any config.rb or that kind of stuff.
AssetsMinify is based on Assetic library.
This plugin is available for download for your site.
