title: Add to home screen functionality using javascript
body: <p>I want "add to home screen" functionality on button click using <code>javascript</code>. My first question is. Is that possible using <code>javascript</code> or <code>html/css</code>?</p>
  
  <p>I have read too many post but did not find any working code. what I found is  user have to do is to go to chrome menu and tab on "add to home screen" or chrome will prompt the user and ask them "add to home screen"</p>
