That last post? Some of you may have noticed that it doesn’t work very well.
The styles applied to the button and the button’s parent element make a difference in how IE (and to a lesser extent Opera) handle the positioned elements.
My current line of attack is to use more jQuery to remove some styles from the button itself and apply them to the inserted span. For Opera, I’m looking at the SVG solution.
This time I may wait until I’ve finished testing before posting.
