title: How to make a 3 column fully responsive image grid in HTML/CSS?
body: <p>What would be the best way to go about making a 3 column fully responsive image grid with a 10px margin on the left/right of the center image (responsive from 1280px all the way down to 320px) in HTML/CSS that has extensive cross-browser support?</p>
  
  <p>Could I use a CSS propert such as: column-count? Is there a better way to achieve this?</p>
