For some reason after I upgraded to El Capitan Quick Look doesn't work anymore for CSS files. I mean, those are just plain text files, nothing fancy. They have been supported in Quick Look ever since I used a Mac.
All my web files, .scss, .php, .html they all work with Quick Look (spacebar) except .css.
