+Viewport adds a couple of extra selectors to jQuery. With these selectors you
+can check whether the element is inside or outside of viewport. To see how it
+works check the demo:
+http://www.appelsiini.net/projects/viewport/3x2.html
+
+The viewport selectors depend on jQuery. Include it in your header:
+
+<script src="jquery.js" type="text/javascript"></script>
+<script src="jquery.viewport.js" type="text/javascript"></script>
+
+Now you can use the following new selectors
+
+$(":in-viewport")
+$(":below-the-fold")
+$(":above-the-top")
+$(":left-of-screen")
+$(":right-of-screen")
