making one square appear in the top right corner of another

According to <http://www.w3schools.com/Css/pr_class_position.asp>, "an
element with position: absolute is positioned at the specified
coordinates relative to its containing block."

I'm trying to do something like that, myself. Place an element in a
position relative to its containing block. Unfortunately, it doesn't
seem to be working:

I could use position: relative and assume that the box will always be
200x200, but that's not a safe assumption. I could also do position:
absolute, using the behavior that it's demonstrating, but again,
that'd be making an unsafe assumption.

Any ideas?
