Ionic 1 responsive grid

ionic-v1
1

I am implementing grid in ionic 1. I want to make the UI fit to all screen devices. How to use ‘xs,sm,md,lg,xl’ ? Whats the solution for supporting UI in multi screen?

<div class="row" >
      <div class="col" ng-repeat="number in latest">
          <img ng-src="{{number.thumb}}" />
      </div>
 </div>
