title: css hover alternative (automatic)
body: <p>My CSS has to change using a transition ,and till now i used <code>div:hover</code> for that.</p>
  
  <p>The transition needs to be activated when you click another <code>div</code>, not when you hover over the <code>div</code> that has to move/change . </p>
  
  <p>How can I do that ?</p>
  
  <p>Thanks</p>
