Hello. I have a mac and use firefox, safari, and chrome but not internet explorer. It just came to my attention that the website I created http://www.partyondesigns.com does not look good at all in internet explorer. The sidebar is missing on the main page. The white background in the container is missing, the menu bar is missing, etc. You can view it correctly in firefox or any other browser but internet explorer does not look right. Does anyone have any idea what I can do to fix this issue in internet explorer?
