CSS DEMOSCentering an image of unknown size in an outer container of known size

Date : 15th October 2006

For all modern browsers

The image below should be centered within the outer gray box without specifying the dimensions of the image


I get lots of emails asking how to vertically and horizontally align images within outer containers when the image size is unknown.

Well this is one answer that works in IE5.x, IE6, IE7, IE8, Firefox, Opera, Mozilla, Safari(PC) and Google Chrome, but does require two different styles, one for IE 5, 6 and 7 and the other for non-IE browsers and IE8.

IE 5, 6 and 7 uses inline-blocks and non-IE browsers use table-cell and vertical-align to emulate the table method.
