I have a very basic 3 column page that I would like to have centered. In every other browser that I've tested, it works fine, however, in IE it gets aligned to the left. Can someone take a quick glance and see what I'm missing?

Thank you!

I forgot to post my html structure. I've removed all the content to just show the design.

looked .... like all true ....

you need to create a body class in your style sheet

body {
   text-align: center;
}

Thanks for the ideas!
Unfortunately, adding the body tag did not fix the issue. :(

Sorry, my mistake, that did fix it.

Thank you very much.

mmm... maybe try adding the text align to your container?

woops..sorry! didn't see you said that it worked on your post below the one that it didn't work... hehe!

Try in container:

padding: 0 auto;
