I am implementing a design that uses custom styled submit-buttons. They are quite simply light grey buttons with a slightly darker outer border:
input.button
I can't comment (yet) so I have to add my comment this way. I thing Mr. David Murdoch's advice is the best for Opera ( here ). OMG, what a lovely girl he's got btw.
I've tried his approach in Opera and I succeeded basically doubling the input tags in this way:
This way the 1st element is hidden but it CATCHES the display focus Opera would give to the 2nd input element instead. LOVE IT!
