雪球滑落的效果

所谓的效果就是如图: 

嘿嘿,很漂亮对吧? ^^

首先,
去设计(Design) > 页面元素(Page Element)>添加小工具(Add Gadgets)>HTML/JavaScript

把以下的代码粘贴进去:
<script>
    //Here you can add your own picture for snow. Just change the url
    var snowsrc="http://1.bp.blogspot.com/-ZhjqZu_ozj8/TjzOYWxIyWI/AAAAAAAABhY/cBGblpOBl9k/s1600/whiteshowNF.png"
    //how many snowflakes there will be (currently 12)
    var no =40;
    //How fast will the snow disappear (0 is never)
    var hidesnowtime = 0;
    //The height the snow will reach before it disappears ("windowheight" or "pageheight")
    var snowdistance = "pageheight";
    ///////////////////////////////End of Settings///////////////////////////////////
    var ie4up = (document.all) ? 1 : 0;
    var ns6up = (document.getElementById&&!document.all) ? 1 : 0;
    function iecompattest()

    function snowIE_NS6()
    {

    }
    function hidesnow()

你可以把红色字体换成你要的图片代码哦 :)
以上的那个代码是白色雪球

这里也有其他雪球的颜色:
