Is there an advanced CSS minifier/compiler that does things like strip redundancy and comma separate identical rules?

Question

For example

input{margin:0}body{margin:0;background:white}

would be shorter written like this

input,body{margin:0}body{back         


        

Answer 1

try LESS.

LESS will automatically recognizes when you save your *.less file and immediately compiles your CSS-Code and will minified. You can create as many files as you want and LESS will observe them all to trigger compilation.

You will only work in the .less files. the Tool will auto compile and save you files as .css
