cssFx adds vendor-specific prefixes to your stylesheets. When the document has finished loading, internal (<style>) and external (<link>) stylesheets are processed, fetching any @import stylesheets as well. It's recommended to bundle stylesheets into one file to minimize request overhead. Once processing is done, a new <style> tag is appended to the <head> with processed properties. Properties for all vendors (Mozilla, Webkit, Opera, Microsoft) are included by default.
