We have a dynamic html page, where users are adding, editing text in a template. It is possible that the user might add text that spills the content over onto another page. Is it possible to shrink it to fit on one page only? If not, are there any other suggestions to combat this?

At the moment there is no mechanism to shrink text to fit a specified vertical height. If you specify a fixed height the text may overlap the page border, but will not break onto the next page.
