WYSIWYGged Out
Someone was probably playing in a WYSIWYG editor to come up with this Monstrosity:
It looks all right in IE, which means two things: 1, that IE is more forgiving of extraneous <span> tags, and 2, whomever built this page looked at it in IE but not in Firefox/Safari/Opera/Anything Else.
Ha! Just kidding. #2 is not necessarily true. It’s entirely possible no one looked at it before posting.
