title: CSS - scrollable div with hidden scroll bar
body: <p>I can't get my navigation scroll to work without scroll bars.</p>
  
  <p>I found many examples here, but they are not working.</p>
  
  <p>I tired parent class with overflow: hidden; and child class with overflow-y: auto;</p>
  
  <p>Does anybody knows what's wrong in my CSS?</p>
