it doesn’t show the facebook login button in Ie6,ie7 pages , don’t know why .
I am using very simple code. you can view the source .
I’m sorry to say that your code is anything but simple. All those tables and table cells make the page hard to debug. You have widths and sizes blowing out all over the place. I don’t want to be mean, but truly, this page could be a lot simpler and neater with a pure CSS layout. I don’t have access to IE at the moment, so I’m afraid I can’t help with that right now.
