Centering web pages… the easy way

I had a great lesson in simplicity this week thanks to the centering of UW pages in the CLF issue. For the UW home page I used the technique described on Maxdesign. What this technique requires is a div#container for it to work. This is great but when it comes to the XTHML/CSS that runs the CLF this requires a number of changes that include:

  • modify body tag to center text
  • insert container div to CSS and XHTML
  • modify right nav values
  • modify #uwlogo values
  • some other thing I can’t recall

In order for it to work on your CLF based pages you would need to:

  • insert a div tag below the body and close it before /body
  • update your template if you didn’t use server side includes

Well after yesterday’s session, Kevin Paxman (Graphics) emails me:

Maybe I’m missing something…but this worked for me as far as I could tell, with 5 minutes of testing in PCIE 6 and Firefox…

 
body {
margin: 0 auto;
position: relative;
}

Then the rest of the position: absolute’s can stay. I didn’t fiddle with PCIE<6, but it should degrade to left aligned gracefully, or you could text-align: center the body and text-align: left the necessary DIVs?

Guess what? It works. AHS and others have implemented this in their custom.css and it works like a charm. So what is the workflow now?

For Web Ops:

  • insert margin and position elements to UWblank.css

For you:

  • nothing.

Wow. Lesson learned, simple solutions often are the best. Now I am not entirely sure why that works for UW CLF based pages. I would think it was too simple, something must be wrong. But it works.

One thing: Watch the tags above your doctype – they throw IE into quirks mode and that is bad. So please make sure no tags come above the doctype.

Another thing: Some on a certain mail list have asked why position:relative in the body tag? Because if I don’t the UW logo will float to the left. The code is valid though.

Yet another thing: Seems Dreamweaver and Contribute don’t like this technique. Working a solution for those tools.
