Multiple distinct pages in one HTML file

Question

Is there any way to have multiple distinct HTML pages contained within a single HTML file? For example, suppose I have a website with two pages:

Page 1 : cl         


        

Answer 1

This is kind of overriding the thing of one page, but... You could use iframes in HTML.

And page1.html would be your base page. Your still making multiple pages, but your browser just doesn't move. So lets say thats your index.html. You have tabs, you click page 2, your url wont change, but the page will. All in iframes. The only thing different, is that you can view the frame source as well.
