HTML: align="center" through CSS

If you need to center one element inside another block element (for example TABLE inside a DIV element) you can use align="center". For example:
<div>
<TABLE width="50" align="center">
...
</TABLE>
</div>

But if you need to use CSS you can do this:
table {
margin-left: auto;
margin-right: auto;
# or just margin: 0 auto 0 auto;
}
