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

I would recommend https://www.npmjs.com/package/gulp-clean-css

if you don't have problems using gulp it's doing exactly as you want
