title: Change only background color of the div using AngularJS
body: <p>I created a list using divs and I want to change only background color of div when user select one from the list.   </p>
  
  <p>Currently I have done this by defining two different css classes with only difference is background color, and i set this style when user selects the div.   </p>
  
  <p>So is their anyway to change only background color without affecting existing style using angularJS?  </p>
