Possible to globally skin form->button css properties?

The button controls for use in CAF use the default browser look and feel. It’s possible to use css properties in normal web-dev to make buttons more attractive (such as the buttons in this forum).

Is there a way in the wm shell/skin/CAF framework to globally style the look and feel of html button controls etc? What is the best way to approach this?

The buttons on these forums are GIF’s. One way to do this is to create the images and use an asynch command icon control. Link the image url to a skin image property
