how can i add an easing/animation/slowly moving to this function? At the moment it just jumps. Now it should move to the "anchor" with an animation.
<script type='text/javascript'> setTimeout("window.scrollBy(0,270);",3000); </script>
Another example with jQuery, uses the easing plugin for some nice effects:
