Real Page Break, how can i do?

Hi, i need to do a Page Break, but not for print, for show the HTML in distinct parts. I have an article divided in diferent page, i insert a special tag that mean PageBreak and when i divide the code the open tag and the close tag are in diferent pages. When i show, this code it's wrong because i.e: i show the last pages i got close tag that cause the entire page go wrong.
I like to make a real page break, that insert a especial text an close all previous tags and open the next tags. How can i do that?
Thanks.
