title: Animate HTML element on scroll position
body: <p>What I would try to do is to animate via CSS3 some HTML when the <strong>scrollbar</strong> reach a <strong>certain position</strong>.</p>
  
  <p>I navigated through <strong>jQuery</strong> plugins founding lots of interesting things such as parallax or harmonic scrolls,and the closest thing I found is the popular <strong>lazy load</strong> which delay the loading of images while scrolling the page.
  What I'd like to do is something like that but with animated <em>div</em> or <em>img</em> or <em>a</em>.</p>
  
  <p>I hope somebody can direct me to some good plugins who can help me.</p>
  
  <p>Thanks in advance.</p>
