How many more threads asking this question are there going to be? With great agony. In most cases, IE users just don't get modern features if we can't work around it. Sites may run slower or need extra steps for them to complete the task. Hopefully IE users will see the same site in a modern browser (anything but IE) and be given enough reason to figure out they need to get rid of that crap browser and use anything else to enjoy the richness HTML5 has to offer.
Or you can use your skills and work around the problems . This is one of the differences between an amateur and a pro .
