直接在首页添加个自定义模块 编辑 点两个箭头的那个编辑代码模式 然后复制代码放进去 确定就好！
雪花飘落的JS代码
N是管雪花的数量，Y是雪花下落的速度，(document.layers)?window.innerHeight:window.document.body.clientHeight;是雪花下落的尺寸，可以改为=(document.layers)?window.innerHeight+100:window.document.body.clientHeight;+100，下落尺寸加大100。
利用JS给网页添加雪花飘落的效果
1、修改部分如下：
?head
??script?src="?Demo/jsized.snow.min.js"?type="text/javascript"/script????????
script
????/**
?????*?This?function?takes?2?arguments
?????*?First?is?the?path?to?the?directory?with?snowflake?images
?????*?Second?is?the?maximum?number?of?snowflakes,?please?do?not
?????*?set?this?number?above?60?as?it?will?impact?the?performance
?????*/
????createSnow("",?60);//目录改为当前目录
/script
?/head
?body
??测试
?/body
/html
2、在该网页目录?下?新添加?四张雪花图片?命名规则（snow0.gif?snow1.gif?snow2.gif?snow3.gif）

苹果Mac电脑使用教程之屏幕雪花飘落特效
雪是冬季的象征，如果想热切感觉到雪花飘落的感觉，你可以来看看小编带来的苹果Mac电脑使用教程之屏幕雪花飘落特效，简单的操作就能够让你的Mac屏幕下起雪来，让你感受到浓浓的冬季气息，而且有节日的感觉。
1、在
Mac
系统中打开
Launchpad
界面
2、在
Launchpad
的【其它】文件夹找到【终端】应用
3、打开终端后，点击它位于
Mac
屏幕顶部菜单中的
Shell
菜单
4、随后在
Shell
菜单中，点击【新建窗口-Ocean】来新建一个蓝色背景的终端窗口，这样可以让屏幕雪花飘落特效更加好看
5、随后在终端窗口里输入如下代码（可直接复制并粘贴到终端窗口里），然后按回车键执行
ruby
-e
'C=`stty
size`.scan(/\d+/)[1].to_i;S=["2743".to_i(16)].pack("U*");a={};puts
"\033[2J";loop{a[rand(C)]=0;a.each{|x,o|;a[x]+=1;print
"\033[#{o};#{x}H
\033[#{a[x]};#{x}H#{S}
\033[0;0H"};$stdout.flush;sleep
0.1}'
执行后便可以看到从终端顶端不断掉落下来的雪花特效了
6、如果想要退出终端，可以按
Command+Q组合按钮，然后再点击【关闭】
