I'm an engineer on Google Documents. We're running into an issue with HTML font
translations in Safari, and I was wondering if you could shed some light.

In Safari, in design mode, if we call execCommand('fontSize', size), where size
is 1...7, we get:

<span class="Apple-style-span" style="font-size: x-small;">8</span>
<span class="Apple-style-span" style="font-size: small;">10</span>
<span class="Apple-style-span" style="font-size: medium;">12</span>
<span class="Apple-style-span" style="font-size: large;">14</span>
<span class="Apple-style-span" style="font-size: x-large;">18</span>
<span class="Apple-style-span" style="font-size: xx-large;">24</span>
<span class="Apple-style-span" style="font-size: -webkit-xxx-large;">36</span>

No xx-small, and -webkit-xxx-large for the largest size.

The problem is, these font sizes (xx-small ... xx-large) render differently
between IE  (which maps xx-small -> 1, x-small -> 2 ... xx-large -> 7) and both
Firefox and Safari (which maps xx-small -> 1, x-small -> 1, small -> 2, ...
xx-large -> ???). Do you know why this discrepancy exists? Is there a better
way to apply font sizes that is more consistent across browsers?
