Hi, thanks! But we have to try to reproduce your problem. Can you describe please step by step, what you want to do and when you encounters the problem. More information about your joomla, php ... would be normal.

why you want to change css. If you want to use JEM RESPONSIVE, please read the instructions inside the downloaded zip-file. you don't have to change the css. The new css for responsive is in template overwrite!
