CSS CSS Basics (2014) Enhancing the Design With CSS Border Radius

border-radius using % or rem.

In the video, it was said that when using percentages, they go off of the dimensions of the element. If that's the case, is there any difference in using rems instead of percentages?

They are quite different.

The % unit is relative to the size of the element.

The rem unit is relative to the base font size. It's completely unrelated to the element size.

I thought rems could be used with anything that accepted a length unit.
