It's not about what's the problem with { width: 55%; margin-left: auto; 
margin-right: auto; } it is that { align: center; } would be much 
shorter and make a lot more sense to a lot more people. When I started 
using CSS with XHTML 1.1 I couldn't figure out why I had to use margins 
to align tables when in HTML I could do that with align="center".
Margins should not be used for alignment. We need to be able to type { 
align: center; } !
And it should not be for tables and divisions only but also for inline 
elements. That way you can center a div while the other things on top 
and under it will remain aligned to the left.
