This is a thing I made using CodePen and CSS. I guess I'll call it "CSS clock animation" or something like that.

See the Pen bgpLBz by Markus Kylberg (@kylmark) on CodePen.0

A simple clock animation I made to use as a loader on Sulkysport. I’m using ems for all widths and heights to make it easily resized by just changing its font size.
