You *can't* and *shouldn't* express "font-size: small" in CSS!
I use following settings in my browser:

Konqueror browser->Appearance->Font size
Minimum Font size: 7 [pt]
Maximum Font size: 10

All this is controlled from the Preferences (Settings) dialog.
If someone want *bigger* fonts for  "font-size: small" , he can tune it in 
this dialog.
For the same reason, default font names (Arial/Helvetica for SanSerif, 
Times/TNR for Serif) are not hard-coded in html4.css
You select font names in Preferences dialog, too.

Is there any list somewhere describing proposed variables?
