fixed vs relative font-size keywords
On page 75, there is a discussion about relative vs. fixed font sizes. Unfortunately, I got some of the facts wrong here.
It turns out that
x-large (along with
absolute-size keywords, not relative-size. So changing the base font-size will not
change elements that are styled with those keywords.
On the other hand,
smaller are relative font-size keywords, and
work as described. The specifics can be found [here in the W3C’s documentation]
Github user bazzaxiv was kind enough to report this and provide the reference. Thanks so much!
