Netflix-Clone-v2: Non-Responsive Layout on Small Screens (Phones)

The Netflix-Clone-v2 interface breaks on phone-sized devices (viewport width < 768px). Observed problems include:
  
- Text/images overlapping or becoming unreadable 
- The layout grid is not adapting to smaller screens
- Movie posters at the end of the webpage, clutter on smaller screens
