CSS auto-correction service?

Question

css

Are there any services that automatically add for example prefixes for different browsers and fix errors in CSS?

Answer 1

Isn't gulp easier to master?
gulp-plumber and gulp-autoprefixer will do the trick.

Answer 2

Everything is very simple - go to the CSS validator and shove your code there. Then take the already corrected code below and replace the old one with it.
It works in 90% of cases, but you always need to make backup copies, as it can glitch.
