2. what do you think about using 100% font size in general?

3. would you use 100% font size on your websites?

Nice find, but it essentially reinforces what has been said before about whitespace (unless its quite old?) But to be fair I haven't used that much whitespace/font-size before. It suits articles well, but not sure if it would be too big for say a forum?

For font-sizes I use this:

body {
/* font-size: 100%; 1.0em = 16px */
font-size: 62.5%; /* 1.0em = 10px */
}
#content {
font-size: 1.3em; /* 1.3em = 13px */
line-height: 1.6em;
}
p {
margin: 1.6em;
}

It allows the user to resize text in IE6, and makes choosing font sizes easier for me as I can still think in px. The only time it falls on its arse is if the user changed the default font of their browser to anything other than 16px.

I don't use px, "small" or % for defining the actual font sizes though, and I suppose the bonus of using a global % age for the body tag, I can then add + or - text size buttons, though I haven't needed to yet.
