Why are you using <font> in html 5?
Well, it's not really OT. The whole code is such a formless mess, I had to home in on something. The second thing to catch my eye was the assorted "class = blahblah" declarations without any corresponding CSS to see what-if-anything the class does. This makes diagnostics a little bit tricky.
All those "code by..." lines imply that you're cutting-and-pasting someone else's code without really understanding what it does. Or what it's meant to do, which is not always the same thing. The obvious place to ask is the person who made the code in the first place, or the site where you found it. There's always some explanatory stuff.
