I am going to be conducting a few interviews over the next couple days to hire web designers for a new project here. What are some questions I could ask the candidates?

Here's what I've got so far:

1. Given this:

<table><tr><td>abcdefg</td></tr></table>

Use inline CSS to make the text red.

2. What is the difference between cellspacing and cellpadding?

3. Can a table contain another table?

4. Can a form contain another form?

5. What does a comment tag look like?
I'd like any questions you can come up with for the interviews.

TIA.
