Q: Bootstrap desktop & mobile layouts push pull on w3schools Im trying to achieve the following. Mockup: http://pasteboard.co/iNg55T4.png
The code below looks good on mobile (xs) but on desktop (md or greater) the positioning is wrong. I have tried all sorts of push/pull but to no avail. Im using w3schools website to play around with their editor and have the code below. 
And using this link and code at w3 schools
