Fix first Div and only resize the second Div - column 3 under column 2

问题

This is actually a follow up question to Bootstrap CSS - Column 3 under Column 2 on resizing

I would actually like to fix the first div and not move it at all

Small devices:

A      column1
grade  column2
       column3

Medium device:

A      column1  column2
grade           column3

Large devices:

A      column1  column2  column3
grade

and only move the other columns on resizing as per the solution to my original question.
