"The value (of the perspective property) can be in pixels, ems, or rems." What are rems? And is the syntax "rem"?

RE. the perspective property: Guil said, "The value can be in pixels, ems, or rems." What are rems? And is the syntax "rem", i.e. is this what the code would look like: perspective; 2rem;

1 Answer

Rem is Root em. The em unit is relative to the font-size of the parent, which causes the compounding issue. The rem unit is relative to the root—or the html —element

rem is correct syntax
