The most common reason that the chatbox will look much larger than usual is a missing doctype declaration.

For your chatbox to display correctly in Internet Explorer, it should look like this:

<!DOCTYPE html>

If you have a strict doctype, it should also display correctly.


The problem usually occurs when you either:

  • Have no doctype
  • Are using a transitional doctype

Try changing your doctype to the one below and you should be right as rain in no time!

<!DOCTYPE html>
