HTML doesn’t have a page break tag. Consider what the term page means in a web document. If each document on the web is a single page, the only way to produce a page break is to split your HTML document into separate files and link them.
Even within a single document, browsers have no concept of a page; each HTML document simply scrolls by continuously. If you consider a single screen a page, you still can’t have what results in a page break in HTML. The screen size in each browser is different. It’s based on not only the browser itself, but also the size of the monitor on which it runs, the number of lines defined, the font currently being used, and other factors that you cannot control from HTML.
When you’re designing your web pages, don’t get too hung up on the concept of a page the way it exists in paper documents. Remember, HTML’s strength is its flexibility for multiple kinds of systems and formats. Instead, think in terms of creating small chunks of information and how they link together to form a complete presentation.
