If some content does not fit a page width, you’ve got two options: either to extend htmlWidth (in the case the content is scaled down) or to narrow the content, using HTML means.

If the downscaling of the content is not acceptable, just enclose the content into a table and set the table width more-less matching htmlWidth parameter.

In DXL scenario the enclosing table is already there – just find it in XSL and change width=”100%” to width=”800″, for example.
