I added a Facebook like button to my website.My website has a fixed div on top of the page(blue color div in the image). The like button is below that(in a div which can scroll) My problem is when the page is scroll down the like button comes on top of the fixed div(blue color).I want to scroll it from the backside of the div.How can I do that? There are couple of screenshots I added

Before Scroll

After Scroll

Here is my code of the fixed div

  <script type="text/javascript">
function got_to_signup(){

    window.location.href = "view/policy";
    }

</script>
<div id="fb-root"></div>
<script>(function(d, s, id) {

      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = "//connect.facebook.net/en_GB/all.js#xfbml=1&appId=368003049941951";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));</script>
