No misunderstanding here gary was mixing it up, leading to a possible wrong conclusion.

The subject: an unknown tag. If it’s just an unknown tag, it won’t get any useful default styling, right? No specific ties to HTML5. But rather with XHTML, previously.

He said: "all html elements make up an inline string without style rules"! NO! But if you choose to ruin the modularization UAs put at your disposal, if you hide the html.css, all that tempering will make it true!

He could, as well, prove false points all day long. He could make an entry in html.css for the unknown element and rule display:block; for it! Now, making it so, he could say "all unknown html elements are treated as blocks"?

So his explanation rocks... at the bottom of the sea.

A simple explanation:

firefox & opera treat unknown elements like unknown elements.

Why? Since they're unknown, they lack the html definition conveying a default style, style that will be further used as the base for default stylesheet rules!

Why they look like inline? That's where his explanation should have excel, rather than going about stupid experiments!

No mumbo-jumbo lynx.cfg, html.css
