[Solved] How to add and remove classes in jq?

Question

Finally i managed to solve this issue..
Actually i was using ‘prefix-free.js’ which was not correctly coded for chrome. Once i changed the browser and run that code on firefox, it worked perfectly. Due to that prefex-free.js i didn’t apply -webkit- or -moz-. Well Thanks all who participated..

EDITED: Sorry that prefix-free.js has nothing to do with this issue. The issue was due to CHROME browser. I have reported this problem to the developers of chrome. I hope they will resolve the issue on priority basis.
