All style tags after the first 30 style tags on an HTML page are not applied in Internet Explorer.

Seriously? It’s been a limitation since IE 4.0 so maybe it’s not as bad as I think it is.
Interesting number though. You’d think it would be 32 or 64 or 65767, not 30. Maybe it really is 32 but 2 are used internally. Who knows. Just be aware!
