title: How to animate things before scrolling to another section?
body: <p>The case is pretty simple: There is a website with several sections. So on each scrolling, another section appears.</p>
  
  <p>Now some sections may have a textblock, which should fly in animated.</p>
  
  <p>If there is <strong>no</strong> animated textblock, it should have the normal behaviour of scrolling down:</p>
  
  <ol>
  <li>st scroll should just scroll down to the next section.</li>
  </ol>
  
  <p>If there is an animated textblock, the scrolling should be in this order:</p>
  
  <ol>
  <li><p>st scroll should animate the textblock; also stay in current section</p></li>
  <li><p>nd scroll then scrolls down to the next section.</p></li>
  </ol>
  
  <p>Is there a simple way to achieve this?</p>
