new tutorial and documentation suggestions

There is a useful JavaScript function called a switch statement. It seems to be very helpful, but I've noticed that Intro to JS does not have a tutorial about it. I made an HTML article on Khan Academy explaining it, and I was wondering if it could be made into a real tutorial article in intro to js in the logic and if statements part. Of course, it would have to changed a bit first.

The HTML editor does not have much documentation. I know that there is a link to the full list there, but having some quick programs is nice. I thought it would be helpful to have some CSS pseudo class documentation on Khan Academy, so I made this.

Would it be possible some of these could be implemented? I think people might find these quite helpful.
