Honestly, I've never really done CSS properly (like, I used bootstrap and hacked stuff over it to make it look like I wanted), and I've been amazed at what I was able to do when I am given a design.
CSS is not hard, design is !

CSS is not hard, but cross browser compatibility is (especially when it has to work in older browsers and browsers with different extensions) :/
