True, but the fault is clearly with older versions of lynx. Later versions
fix that bug.

Right. There can be no tags inside <STYLE>

HTML comments are always comments and are never ignored by an HTML parser.
A browser that knows about the style element will not see the comments
because it simply skips over the non-html portion, ie until it sees </style>

What is inside the <style> element is not HTML. Its a stylesheet, using
whatever language the attribute said it was:

<style type="text/css">

No-one changed the rules for comments. They already are complex, true,
but that is a 'feature' inherited from SGML. But CSS has not made them
more complex or altered them at all.

What it has done is allowed HTML comments *inside CSS* where they
are ignored by the CSS parser.

Yes, it can be written in the tags, like this:

<H1 style="color: blue">stuff</h1>

No, you can't do that. The style attribute does not have a selector,
because the element with that atttribute acts as the selector.

I suggest you get the final, up-to date version of the CSS1 specification
because working from old drafts is dangerous for authors and highly
dangerous for implementors such as yourself.
