It does not affect the position of line boxes, the flow of elements, or anything else. For example, assuming that text wrapping results in the following text in a line box, text-align would determine how it was aligned within said line box: the words of a sentence. Given text-align: left, the text that has been determined as being in that line box would be displayed thus: +-----------------------------------+ |the words of a sentence. | +-----------------------------------+ Given right: +-----------------------------------+ | the words of a sentence.| +-----------------------------------+ Given center: +-----------------------------------+ | the words of a sentence. | +-----------------------------------+ Given justify: +-----------------------------------+ |the words of a sentence. | +-----------------------------------+ (since text is not justified unless it fills more than one line box. Note how text-align only affects alignment, not anything else. > Now, IE 5.5 would align "childDiv" in the middle of the > page (it's half the parentDiv, so the alignment would be > 25%-50%-25%). No that would be margins. Margins are what affect the position of block elements. To centre a block, you would specify margin-left: auto; margin-right: auto. > If Mozilla doesn't handle this as it should, it would be great if > you let this be known on the above bugzilla page.

Although I think this is probably deliberate user-friendly behaviour, in the same way that it allows text-align: center to affect the position of tables.
