Sorry not sure where to change this. Do I change the News Pro module settings? I tried changing template.css in Module Class Suffix to elegant.css and no change. I can change it in the Menu Module and it does change the style.
OK. Create a JoomlaXTC HTML Module with the heading you want, turnon the heading for the JoomlaXTC Delux News Pro and use the HTML module for the heading with, as jayblaq said, elegant in the 'Module Class Suffix' box.
