Hey there,
Are you referring to EasySocial or Komento?
May I know which page in mobile view are you referring to so that I can understand it better?
For your information, you can add custom CSS code into
Backend > Themes > Custom CSS to do that.
By the way, can you include your site's access and FTP's access once at
http://stackideas.com/dashboard/site so that we can have a better check for you?
