Background
@Jdrewniak has brought up a very good point recently:
I can see the utility @font-size-base going forward, even with rems.
That leads me to another question though. It seems like if @font-size-base ’s main responsibility is to derive other font-size values, then it should mostly stick to that role, and we should use variables like @font-size-small...medium...large in actual font-size properties. I guess what led me to ask this question is seeing @font-size-base being equivalent to @font-size-medium and wondering which one to use.
Goal
Clarify usage intention of the magic token.
Acceptance criteria
- Documentation updates to make intention clear
- Update Codex code base to replace wrong usages of px featuring token for accessibility reasons
