Yes there has to be a width smaller than the parent in order for it to 
be centered. { align: center; width: 60%; } would just be better than 
having to use margins. And also align would be easier to understand. 
There is nothing wrong with margin.
Using margin is fine, it works, and that's good. But just because it 
works doesn't mean it's the best way.
In my previous examples I never thought of widths as it very obvious 
that you need a smaller width in order for something to be centered.
