Xtreme and Web Designer are WYSIWYG web site designers which use absolute positioning CSS html.
Dynamic pages are not WYSIWYG - so Xtreme and Web Designer's pages are static width.
However, John Horn (aka: Covoxer, one of the Xara developers) has created a number of free placeholder code snippets known as 'Tweaks'. In the set there is one tweak which can be used to create dynamic page *length* pages, but not width.
So in short, no - you can't do this with absolute positioning css.
