Strictly speaking, do style tags need to be inside the head of an HTML document? The 4.01 standard implies that, but it's not explicitly stated:
The STYLE element allows authors to put style sheet rules in the head of the document. HTML permits any number of STYLE elements in the HEAD section of a document.
I say "strictly speaking" because I have an app that puts style elements inside the body, and all the browsers I've tested with seem to use the style elements. I'm just wondering if that's actually legal.
