Why won't an HTML link work inside a transparent bordered div?

I originally setup a single <div>, z-indexed above other content. I couldn't click th开发者_C百科rough because even though it was transparent, it wasn't clickable.

I tried to split the pieces apart - sides, corners and all, but the link is still not clickable.

Here's my page: http://4amnew.4thavenuemedia.com

Any ideas?

adjust your css:

#twitter
{
   z-index: 200;
}

Give Z-index:250 for #logo id

#logo {
height:136px;
left:90px;
position:absolute;
top:0;
width:240px;
z-index:200;
}

IF you want to test link also clickable means give z-index:210; for #twitter
