Page numbers in HTML aren't possible because there are no "pages". A page ends at the end of a piece of paper, and this doesn't exist on a computer monitor. A topic that is longer than a screen just scrolls down until you reach the end. Effectively, every topic is a single page, so every page number would be 1, which wouldn't really make sense.
If you print the browser adds page numbers automatically.
