Automate the pagination of web pages

A lot of articles of the web (for example, this one) document how you can present a web page as a series of screen-sized pages. In most cases, the page author has to provide the pagination (in form of DIV elements, for example). In the InformIT article Automate the Pagination of Your Web Pages, I'm describing a method of generating the pages from linear text automatically in the browser, based on (for example) heading elements.
