It might seem like no big deal that the web gained two new units, lh and rlh, to reference line heights. Support shipped in every browser in 2023 without much fanfare.What the fuck, this is huge! The only way before was referencing the line height from a variable, but there's never a guarantee that it really is the current line height.
