How to Minify CSS to its Absolute Minimalistic Essence?

Dear folks, staring at the minified CSS I put together so proudly the other night, I desparately tried to remove more chars here or there, like those wasted whitespace: " " meanwhile the more I stared at this code, the more I started to see patterns, clearly emerging from these bodies, asif this was the absolut开发者_运维知识库e minimum, plus some hidden message Now let me get to the point for this question is already too contaminated with nonvital letters already: Is there a way we could further minify my otherwise humungously gigantuous monster css file into a more bandwith friendly, really small file? Much appreceated!

1. If your css is hosted on the same site as your images, use relative paths in your url()s: background:url(/path/to/file.png)
2. Use shorthand where applicable: margin:0 instead of margin:0px 0px 0px 0px
3. Try running the CSS through a real minifier such as the YUI Compressor
4. As a last resort, shorten your class names in the CSS and the related HTML
5. Pass it to the left...

You've got a bunch of "0px" values in there, just make them "0" to save a couple of characters each there. Also, your negative text-indents could be -999em instead which saves a couple of characters and equals roughly the same depending on the base font-size.

And as @ithcy said, use short relative paths or re-host at imgur and reference as url(//imgur.com/name.jpg) instead will save some bytes too.

Edit: Duh, I just re-read @ithcy's answer and it mentions most of what I said anyway.
