Ultimate facebook login iframe too wide

Ultimate facebook login iframe too wide

Please let me know how to make smaller I Can't find the code in fire bug if I change the width to 495 its good
element.style {
border: medium none;
height: 200px;
overflow: hidden;
width: 550px;
}
But I can't find width: 550px in the php code since its an element style
a picture is worth a thousand words

Before in Fire Bug

After in Fire Bug changing Width to 490
