给自己的网站换个圣诞节的气氛背景🎄🎅

博客好久没有更新干货了！🎄来了~ 站长想换个场景可以试一试哦！

代码是拔来的，参考：红旗Linux 官网哦~  分为3部分，分别是html，js，css 代码！

参考站点：https://jike.info/

HTML代码

<div id="christmas" style="position: fixed;z-index: 9999;background: rgba(0, 0, 0, .3);"><div style="position: fixed;left: 0;bottom: 0;width: 100%;text-align: center;"><img src="https://www.chinaredflag.cn/a_data/image/6.png" style="width: 100%;height: 100px;z-index: 9999;" alt=""></div></div>

JS代码

依赖jQuery

    jQuery("#christmas").click(function(){
        jQuery(this).hide()
    })
    for(i=1;i<=200;i++){
    top1=900+Math.ceil(Math.random()*100); 
    left=1+Math.ceil(Math.random()*99); 
    src=Math.ceil(Math.random()*4); 
    s=5+Math.random()*13; 

    h=3+Math.ceil(Math.random()*10); 
    console.log(src)
    newf=jQuery('<div class="flake"></div>').css({
      "-webkit-animation-duration":s+"s",
      "-moz-animation-duration":s+"s",

  })
    jQuery("#christmas").append(newf);
  }
  for(i=1;i<=50;i++){
    top1=900+Math.ceil(Math.random()*100); 
    
    left=1+Math.ceil(Math.random()*99); 
    src=Math.ceil(Math.random()*5); 
    s=5+Math.random()*13; 
    h=20+Math.ceil(Math.random()*30); 
    console.log(src)
    newf=jQuery('<div class="flake">'
      +'<img src="https://www.chinaredflag.cn/a_data/image/'+src+'.png" style="width:100%">'
      +'</div>').css({
      "-webkit-animation-duration":s+"s",
      "-moz-animation-duration":s+"s",
      "-ms-animation-duration":s+"s",
