But what if I have nesting font elements? For example:
<font size="4">A<font size="-2">B</font>C</font>
The CSS 2 spec says that the scaling factor between font sizes is 1.2 (120%), but the CSS 2.1 spec revised that:
"In CSS2, the suggested scaling factor for computer screen between adjacent indexes was 1.2 which still created issues for the small sizes. The new scaling factor varies between each index to provide better readability."
which is why I'm wondering if I should rely on percentages.
BTW, I'm actually not creating a webpage - I'm just creating some sort equivalent of HTML Tidy. So it's not me who's using the font element.
