Demo pages missing html/header tags

[pvdz]

The (currently private) demo pages are missing the html and head tags. I know they can be omitted but think we should give a correct and complete example and write proper and complete code. That includes html.

It's not clear what demo pages you're referring to. Also, if it's valid HTML, what's the problem?

The pong game, for instance.

The problem is that this is an example. I will refer to this as "the semi-colon debate".

When showing examples, show proper examples. Just because you can omit tags from the source doesn't mean you should. Especially when it has a good chance of confusing new people. Be proper, be complete. Very especially when you're doing examples.
