trovster 11 December 2005 Nice idea to block ads, but currently AdBlock for Firefox does a great job at that already. What other browsers support user-defined stylesheets? Is IE7 going to? If not, then this is kind of pointless. I can’t wait to make use of this selector and other more basic ones such as adjacent and direct descendant. It could be useful on forms, to add icons for certain inputs. It’s already been documented for external links too. Ooooh, I can’t wait!
