Bootstrap right Column on top on mobile view

Answer 1

In Bootstrap 4, let's say you want to have one order for large screens and a different order for smaller screens:

  

    

      This column will be ordered second on large to extra large screens
    
    

      This column will be ordered first on large to extra large screens
    
  

You can omit order-1 and order-2 above. Just added for clarity. Default order will be the order the columns appear in the html.
