/font-size:\s*1\s*(?:px)?\s*;/i
I'm not enough of a CSS expert to know what would happen if I threw "em" and "ex" in there, but I'm afraid that might create some false positives...
1em would be pointless for obfuscation purposes, as it would be equivalent to no font-size setting at all. (In CSS, an em is the current line height.)
1pt might be useful to look for, though.
