Created attachment 774643 [details] demo.html User Agent: Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.16 Steps to reproduce: See attached file - this is a CSS rendering bug. Actual results: Child elements are not centered in the parent elements. Expected results: See attached file - it's expected that this will render with all child elements of the "li" centered in a minimum 100px "li". The child element should take up the full width of the parent, with minimum 20px padding on each side.
