Hi, Michael... I'm new to designing layouts via CSS, too, but maybe I can help here.
Let's break down "margin: 0 auto;"... That's really short hand for Margin-top: 0; Margin-bottom: 0; Margin-left: auto; Margin-right: auto; When used in that particular shorthand, the first place attribute, in this case "0" is for the top and bottom margins. The second place attribute, in this case, "auto", is for the right and left margins. So what you're doing, in effect, is creating 0 margin or no margin for the top and bottom of the container and margins for the right and left of the container that are equal in size based on the size of the window showing your page. Concerning the "body { text-align: center; }" CSS, it's true, if my understanding is correct that all text in the body will be centered with that code, but that's why the others recommended putting "text-align: left" in the #container code. Since everything on the page will be placed inside the #container, all text on the page will then be left-justified. Does this make sense? I hope all my comments are correct and helpful.

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.
