I have multiple pages being pulled together into a single page. Some of these individual pages have their own html, head, and body elements. Is it detrimental to the performance of the page to have these? It seems that the DOM is correct (only has a single of each element) in FireBug.
First: don’t do that.
Browsers are very tolerant if it comes to parse HTML, therefore firefox has a valid DOM in your case. Having multiple html, body and head tags does not affect the performance of the page parsing. But be aware that the browser will propably run in a quirks mode and affect the rendering of any of your elements.
Anyways this is totally against any standards and you should avoid producing such pages. Some browsers could possibly reject to display anything of your site. That may be some browsers you havent thought of, a text browser, or a lightweight browser on a older mobile phone for example.
