I recommend against using the <center> tag as it is deprecated as of HTML 4.0. Some of the examples I gave might even be deprecated. The recommend using style sheets now-a-days. But browsers still recgonize all the deprecated alignment tags, and they are still widely used, so it doesn't hurt.
i use td align="center" when im aligning a list of things or just a whole cell, but most the time it's just one line of text, and <p align="center"> adds too much spacing..
ok. as i read this i was thinking "why are they saying to use the deprecated align tag?" then "why the dprecated in html 4.01 and unsuported in xhtml center tag?"
use what jam said. in a year or so it'll be the only one that works...
I doubt that'll it'll be the only one that works in a year. They are in such wide use that I think it'll be several years before we even start to see them go away and become unsupported. However, you are correct in that it should be done using the STYLE tags; just to be on the safe side.
Up until a few months ago I never used style tags. Now my entire site (or most of it) is all style tags. Makes it easier to read anyways.
