****The code below does not appear color coded but displays fine.**** The markup validator errors are keyword copyright and classification are not registered and align values are obsolete. Not worthy of harming color coding that I'm aware of. Below is the code that gets color coded. I see a difference in the first few lines, if you know why one is color coded and the other is not, please point it out.
