in aet.css you have #banners
{ z-index: -1; .....}
by assigning a negative z-index you make it display behind that the document and thereby it becomes unclickable.
Imagine that the viewport, as a piece of glass, (like a window). on which the document is attached.
elements with zero, no, or positive z-index will be placed i front of the glass, the higher z-index, the closer to you.
While negative z-indexed elements will be displayed behind the glass.
Have you ever tried to slap a fly sitting on the outside of a window, from the inside?
Maybe you have, but I bet you, in that case, were unsuccesful.
I know you have the negative z-index to put #banners
behind #myslidemenu
Instead you can put #myslidemenu
in front of #banners by giving it
z-index:1
or by swapping the code blocks.
Code:
<div id="myslidemenu">...</div>
<div id="banners">...</div>
to
Code:
<div id="banners">...</div>
<div id="myslidemenu">...</div>
Any way, you have to remove the negative z-index in order to make it clickable.
beside that you have a tried on other element to assign
z-index:10px; z-index is not a
distance, but more like a
rank, where those with the lower rank must go first.
