title: How to scroll down on click button 1 time
body: <p>i want to know how i can scroll down only 1 time from homepage on click of button, if already scrolled then on click button to don't scroll down?</p>
  
  <p>I'm suck with jQuery and i don't know how to do it.
  Currently using this code but its always back at #what-is-it id so i don't like this:</p>
  
  <pre><code>  $("#scroll").click(function() {
    $('html,body').animate({
      scrollTop: $("#what-is-it").offset().top},
      'slow');
            });
  </code></pre>
  
  <p>if you have solution with javascript its also welcomed.</p>
  
  <p>Just want to scroll down if users is on homepage? And if he back at home page make button again scroll down him.</p>
