Thank-you, Josue, and also David, for your helpful replies. I've come across this code before, but not - yet - in Eric's book (it's a pretty dense study, for someone starting from scratch!). I gather that "{margin 0 " refers to positioning, and (maybe) means the margin should be at maximum left. But I don't understand how "0" and "auto" work together. I've also read that "body {text-align: center;}" requires explicit text-align statements in all children where one doesn't want text to be aligned to centre.
I've experienced a few frustrations with Eric's book: for one, the Index is pretty sparse -- for example, I can't find any reference to 'centering a block element vertically'. As well, there are almost no references to how to solve particular problems (eg, vertically centering a block element) -- I had to find those in other texts (eg, Web Design In A Nutshell). That's why I greatly appreciate these replies! All the best, Michael Hey, Michael, create a container for your layout (a div that will house everything else). Use this code, assuming that div is called container body {text-align: center;} #container {margin 0 auto; text-align: left;} This is covered in the book. Maybe in the chapter on positioning.
