Hi syedrazi,
Please remove all stylesheet files on your page, does it work?
What I mean the stylesheet is like below
<link rel="stylesheet" href="xx.css" type="text/css" />
If it works, please add the stylesheet back one by one to find out which one cause it. Then please post the code of this stylesheet file which cause this issue, I will check it and get back to you as soon as possible.
Regards,
Ken
