<script src="hoge/jquery/1.8.3/jquery.min.js"></script>
<script src="hoge/snowfall.min.js"></script>

<script>
    $(document).ready(function(){
        snowFall.snow($("section"),{
                minSize: 1,
                maxSize: 8,
                round: true,
                minSpeed: 1,
                maxSpeed: 3,
                flakeCount: 120
                });
