Q:

CSS equivalent of 

I want to set <Font size="+0"> in a lot of places so I want to set it in the CSS. Is that possible?
I tried font-size: +0; and that was a huge failure.

A:

Just found the answer! It's:
font-size: medium;

I found it based on a few links and a little bit of trial and error:
HTML Style tag equivalent of "font size+2"

<font size="+2"> is equivalent to font-size: x-large;

Then I look for possible equivalent for <font size="+0">
