I'm not quite sure, what you want to express with using that term.
I mean to express a core part of the CSS spec that deals with font size. If you're going to tinker with CSS, you should know about this. They call it "absolute size," but it's a semantic designation:

[ xx-small | x-small | small | medium | large | x-large | xx-large ]

The following table provides user agent guidelines for the absolute-size mapping to HTML heading and absolute font-sizes. The 'medium' value is the user's preferred font size and is used as the reference middle value.
See also "smaller" and "larger", which mean "go up/down one size."

False, as noted above. Every UA - that's User Agent, whether we're talking about a browser, dedicated e-reader, or app - is expected to maintain seven distinct sizes, although six of them are usually calculated from one "normal size" baseline. The ratio between them can vary between UAs, and using the UA's interface to say "make it smaller" or "make it larger" affects all seven sizes.

You are aware that defining text as being "1em" in size is pointless, right?
