I used CSS to align my logo with the navigation bar in 7.0.  It worked great, but now I need to hide that navigation on mobile.  Please help.

Hi there, you can use media query like so

To add CSS, go to Design -> Custom CSS
 

@media screen and (max-width: 767px) {
  header#header { 
    display: none !important; 
  }
}
