I remember this on a older post.Because most people I have are government employees and many still have IE6. At least several months ago. You did warn us that you may not be able to get all the features to work on all browsers.
I thought you were going to attempt to plug something in that would be a simple interface display for those that did not have compatible browsers. Like for mobile phones Etc.
I agree IE6 should go away but many people have no control over what browser they use at work. The IT department decides.
Thinking out of the box.
Maybe have a user/admin setting that will direct specific browser types to a downgraded display style. When the specific browser visits the page they are redirected to the different display.
