When using the like or send widget on a Fan Page (no mater if you use iframe tag or fbml for it) the overlay for commenting is positioned always to the right. see http://twitpic.com/4q7ggi for example.
I cant find a way to get the widget to respect the 520px boundary of the facebook tab. see http://www.facebook.com/pages/Ludwig-Test/127771653944246?sk=app_101150316644842 for an example. Anyone an idea how to solve this ?
TIA Rufinus
Try adding this to your css:
.fb_edge_comment_widget {
margin-left: -350px;
}
This will move comment box to the left, but the little arrow pointing to the button will move too (which you could try to cover with another element). It will only work if you're using XFBML, not an iframe.
Here's an example.
