I used firebug facebook fanbox, as I want to get rid of the borders, one border is all around it, 2nd and 3rd both are on top.
here is the code that i got from firebug but still when I implemented it in my CSS even with !important it didn't work.

Code from Firebug

.fan_box .connections {
border-top: 1px solid #D8DFEA;
min-height: 150px;
padding: 10px 0 4px 10px;

When i change it using firebug then it works but when I use it in my CSS, it doesn't work.
Here is the link to the testing page where this FB fan box exists http://bloghutsbeta.blogspot.com/201...ng-author.html

And this is the image just to clarify which borders i am trying to get rid off
