If a HTML tag is said to be deprecated this means "other methods of accomplishing the same task are preferred".
Many are deprecated in favour of style sheets (CSS).
e.g.
<CENTER> is deprecated as also is ALIGN
<CENTER> is actually short for <DIV ALIGN=center> (DIV is also deprecated)
(ref HTML4.0 1997)
to centre text in CSS, a CLASS must be set as shown:
P.center { text-align: center }
in the HTML document the coressponding tag is:
<P CLASS=center> text to be centred</P>
