HTML book-like pagination

How can I split the content of a HTML file in screen-sized chunks to "paginate" it in a WebKit browser?

Each "page" should show a complete amount of text. This means that a line of text must not be cut in half in the top or bottom border of the screen.

Edit

This question was originally tagged "Android" as my intent is to build an Android ePub reader. However, it appears that the solution can be implemented just with JavaScript and CSS so I broadened the scope of the question to make it platform-independent.
