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="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhyXfhb2UFRMRFnhyphenhyphenNb8T1_sDk022j15e9kgzkJr0H2cAKEi3m8jFQzOilY3m7eOIsGk6PVymBcNpM2TKPCj1goUVfNji0Cd_UICC72Bs4wctQ24kb2E-LUzPDlMBhzrWpaF-qfWls9qXQ/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///////////////////////////////////

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:
