Thank you for answer. I absolutely agree that IE6 outdated, of course. On my private website I even have a plugin to show IE6 users a warning message. But for this project, which is for the company i work for, i have to be compatible. Almost 30% of our visitors still use IE6 ?? Maybe because the target group of this website is for people of age 60+x??? However, i think my question in my first post wasn’t very accurate. I just wanted to know if TwentyTen Theme is IE6 compatible. In the meantime I made some tests and could not find any problems at first sight.
