How about a pointer to something concrete that is legacy (an API)? Note that in general, anything you can do with CSS requires some sort of programmable API, even though you manipulate it with CSS.

I think SWT with CSS is my focus. The legacy, itself is the problem:) also not sure what Kevin means:) Thank you!
