Initial Problems with Keyword Implementations

The seven font size keywords might have been implemented correctly and uniformly, but they were not. Unfortunately, the keywords were ineptly or incorrectly implemented in the first browsers that attempted to support them—although, in one case, they were correctly implemented with results so bad, they actually caused a subsequent version of the CSS standard to change.

Whereas Netscape 4 largely ignored CSS keywords, Netscape 4.5 and higher and IE3 rendered them at illegible sizes. For instance, Netscape 4.5 and IE3 rendered xx-small at six pixels—three pixels below the threshold of legibility.
