margin: auto problem in IE

mightypants · 11-17-2008, 10:23 PM

I tried to use the following code to center a div on a page. It works in FF, but not in IE. Any ideas?

Code:

#supportBtns {
	margin: auto;
	width: 400px;
}

Thanks.

Put...



margin-left: auto;

margin-right: auto;

width: 400px;

instead.

jlhaslip · 11-18-2008, 03:54 AM

margin: 0 auto will work.

You need a valid doctype at the top(to turn your document from quirks to standard) to work this in IE.
