tooltip css/html

I’m trying to create the affect of a tool tip with a triangle pointer on top of an unordered list. To create the triangle, I thought I would just create a square div, rotate it 45 degrees, and give it the same background color as the unordered list.

As you can probably guess, this works great in everything except in IE. The problem I’m having is that it seems that the overflow is hidden on the ul, so when I position the pointer div half outside of the ul to create the triangle effect, the top half of the div is hidden.

I have tried to change overflows and z-indexes to get this to work, but no luck. I’m thinking it has to do with the gradient filter applied to the ul, maybe that applies an overflow rule? I know I can probably just move the pointer div o开发者_如何学Goutside of the list, but this will be display on hover of another element, and I’d rather just display the ul on hover, instead of the ul and the div.

Does anybody know how I can fix this?

NOTE: I added borders to the rotated div to make it easier to tell what I'm talking about.

That's a lot of brain damage. Personally, I'd go with a solution that's already been through all this runaround. Try QTip

I don't think there is a clean solution.

Choose between these workarounds:

• Remove the filter rule.
  • Forget about the gradient in IE; or
  • Make an image to replace it.
• Wrap the ul inside a div, and move some of the styles that were on the ul to the div.
  • Instead, give the ul the gradient background.
