I've been thinking of "text-align" as "Horizontal Align", when David's point seems to be saying that it also applies to vertical languages. It doesnt change my thought that something is needed, but now I'm thinking that we need a new horizontal positioning method too. This doesnt make the case for using "position:center", because what Lachy said is also true- we should be able to position text visually (by block) in any of 9 points. I dont understand how a seperate vertical justify would work on non-vertical languages. I think that text-align still has its own place, related to text itself, but a seperate visual alignment property should exist. I dont see how aligning a block vertically would require a height any more fixed than normal rendering in which you are left with un-equal margins. Usually when the height of a column depends on the length of content in another column- cases in which you are unable to provide fixed margins or absolute positions, are the times when you would want to use vertical-centering. That is, not only do I not see why it would require fixed-height, but I dont see that there is nearly as much (though it still very much exists) need for it when you do have fixed-height. I'm not really certain that I'm reading what you are saying correctly.. it seems to be written backwards. It sounds more like you mean to say "You would only want vertical-align:center if you have forced your column to be higher than the expected text to begin with" Which I suppose it true. I wouldnt call it "fixed height" in all cases, but having a background-image always display in full has never been a problem with regaurd to horizontal-alignment of text. Sometimes things overflow. I was under the impression that overflow rules existed to handle that- for example, stretching the containing-block and ignoring vertical-align completely (just using padding/margins instead) Which is exactly how it should be. I would love for my text to start in the middle of a block, and as it fills in, to spread out with equal margins on the top and bottom, until I type something as long as this (we can call that length "too long") and the block is forced to expand, using the defined values for padding, rather than the vertical-alignment and min-height values. This might also bring up a need for an "overflow direction" directive (horizontal|vertical|both), but that would be subject for another post. Shouldnt we in the end, be able to align and position our text in all the ways we currently can using tables? I've seen a lot of CSS pages which say that using tables for layout/positioning is a bad thing. Until CSS can emulate all that tables can do, I can't see that as the case. -- ----------------------- Vincent Starre thebitman@comcast.net
