          <li><a href="#resorts">South Lake Tahoe Resorts</a></li>

Hi Amrit,

It looks like you haven't closed out your style rule for the .group:after selector just above your media queries. As you'll know you can't nest styles inside each other... so just have a look and see which curly braces should be matching together.
