如何在百度空间做个下雪特效

分类: 电脑/网络百度百度空间

解析:

给你一个很漂亮的，源程序也很短。把下面那段放进BODY就行了。

style

.drop { position: absolute; width: 3; filter: flipV(), flipH(); font-size: 40; color: blue }

/style

script language="javascript"

snow = false; false-rain; true-snow

snowsym = " * " These are the symbols for each

rainsym = " * " You can put images here.

howmany = 15 How many drops/snowflakes?

/**************Do not need to change anything below***********/

if(snow){sym = snowsym; speed=5; angle=6; drops=howmany}

else{sym = rainsym; speed=3; drops=howmany; angle=6}

movex = -speed/angle; movey = speed; count = 0;

function moverain(){

for(move = 0; move drops; move++){

xx[move]+=movex; yy[move]+=mv[move];

hmm = Math.round(Math.random()*1);

if(xx[move] 0){xx[move] = maxx+10;}

if(yy[move] maxy){yy[move] = 10;}

drop[move].left = xx[move]

drop[move].top = yy[move]+document.body.scrollTop;

}setTimeout('moverain()','1')}

/script

script language="javascript"

if (document.all){

drop = new Array(); xx = new Array(); yy = new Array(); mv = new Array()

ly = "document.all[\'"; st = "\'].style"

for(make = 0; make drops; make++){

document.write('div id="drop'+make+'" class=drop'+sym+'/div');

drop[make] = eval(ly+'drop'+make+st);

maxx = document.body.clientWidth-40

maxy = document.body.clientHeight-40

xx[make] = Math.random()*maxx;

yy[make] = -100-Math.random()*maxy;

drop[make].left = xx[make]

drop[make].top = yy[make]

mv[make] = (Math.random()*5)+speed/16;

drop[make].fontSize = (Math.random()*10)+20;

if(snow){col = '#336699'}else{col = 'green'}

drop[make].color = col;

}

window.onload=moverain

}

/script

一定是的啦。。行不行瞧瞧吧

下雪的特效怎么实现html

要么用js做，要么就做成把循环动画或者视频效果转成gif格式的，我以前都是用gif来做的，这样会比较快也简单，而且下雪动画做成循环模式一般文件也不会很大

HTML下雪代码
