Minify CSS files


Use a tool like YUI Compressor to remove unnecessary spaces and line breaks. Google’s Apache mod_pagespeed can also automate this operation.

You can use the Yahoo’s YUI Compressor specialised filtres to: - remove comments and white spaces - remove the last semi-colon - remove extra semi-colons - remove empty declarations - remove units of measure when using 0 values and reduce multiple 0s into one - remove 0 for values less than 1 - convert RGB colors into hex values and reduce 6-digit hex values to 3-digit values - remove extra charsets - optimize the alpha layer’s opacity values in Internet Explorer - replace none with 0
