See the Pen Sunset - CSS Animation only by Sher Minn Chong (@piratefsh) on CodePen.

Instead of working on my next project, I decided to spend Friday (which are optional days at RC, yay!) making a sunrise/sunset animation with only CSS (and HTML, but no images). All shapes were created with CSS. My code is really messy right now though, will refactor soon!

CSS is so cool, augh.
