Being from the 1990's, I like to use tables and the good ol' <center> tag to control my layout. Apparently, that's not polite any more. When I get my CSS Guru 9th-Dan Black Belt certification, I'll let you know why.
In the meantime, the totally modern way to centre a block, I learned today, is to give it a fixed width and set left and right margins to "auto". Thus:
.centred {
margin-left: auto;
margin-right: auto;
width: 10em;
}
The block containing this text is centred relative to its parent. Note that the text itself isn't centred. Use
text-align:center for that.
The difference, afaict, is that nowadays the element to be centered is responsible for its centredness, whereas in the old days, the element's parent decided how the child would behave. Very modern, them dudes at w3c. I try to let my children decide how to behave, too. Who would have thought CSS teaches family values?
There is much more presentational HTML to CSS mapping info there :
