Below are two types of submit buttons inside a form. The second one is floated left. Only in Opera 8 or 9 does this cause the button to lose its style! Firefox 1.5 and Internet Explorer 6 show both buttons the same.
Note also that the floated button requires only a single-click in Opera 8 to activate an alert. In Opera 9, you have to double-click!
