Superscript styles

I was looking over my truck page tonight and noticed that superscripts were in the same font-size as the main text in my Mozilla 1.3 browser. This looked really odd to me. Separating the content & meaning from the presentation, the size doesn't matter as far as the meaning of the document (for a text-to-speech reader, or a program analyzing the page). The default user stylesheet of Mozilla kept the font-size the same. I slapped the following into my site CSS:sup,sub
{
font-size:75%;
}Super/sub scripts used to look ^like_this, now they look ^like_this. A little better I think. And if I decide ^{to nest them} things get really interesting.
