All internal links would scroll Smoothly.

Usage :

Include the js file

<script type="text/javascript" src="smoothScroll.js"></script>

Add this script after the body load. Ideally one may add this just before the closing of body tag.

<script type="text/javascript">
        smooth_scroll.init();
</script>

If there is a fixed header, pass the id of fixed header as config.

<script type="text/javascript">
        smooth_scroll.init({
            header_id : "page-header"
        });
</script>

If there are links that should be ignored. Pass an array to ignore those links. Example

<script type="text/javascript">
        smooth_scroll.init({
            header_id : "page-header",
            ignore_links: ["page-header"]
        });
</script>
