兔年打造红包雨，玩转新年喜庆氛围

在喜气洋洋的兔年春节，红包雨无疑是最能增添热闹喜庆氛围的元素之一。借助互联网技术，我们可以轻松打造出红包雨效果，让这个兔年更加别具一格。

CSS3与JavaScript携手共创红包雨

要实现红包雨效果，我们可以借助CSS3的动画和JavaScript的交互功能。

具体步骤如下：

1. 创建HTML文件

<!DOCTYPE html>
<html>
<head>
<style>
#redPacket {
  position: absolute;
  width: 50px;
  height: 50px;
  background-color: red;
  border-radius: 50%;
  animation: fall 2s linear infinite;
}

@keyframes fall {
  from {
    top: 0;
  }
  to {
    top: 100%;
  }
}
</style>
</head>
<body>
<div id="redPacket"></div>
<script>
function createRedPacket() {
  var redPacket = document.createElement("div");
  redPacket.id = "redPacket";

  redPacket.style.position = "absolute";
  redPacket.style.width = "50px";
  redPacket.style.height = "50px";
  redPacket.style.backgroundColor = "red";
  redPacket.style.borderRadius = "50%";

  document.body.appendChild(redPacket);

  redPacket.style.animation = "fall 2s linear infinite";
}

createRedPacket();
</script>
</body>
</html>

2. 添加红包雨效果

<div id="redPacketRain">
  <div id="redPacket1"></div>
  <div id="redPacket2"></div>
  <div id="redPacket3"></div>
  <div id="redPacket4"></div>
  <div id="redPacket5"></div>
</div>

3. 设置红包雨样式

#redPacketRain {
  position: absolute;
  width: 100%;
  height: 100%;
  overflow: hidden;
}

#redPacket1, #redPacket2, #redPacket3, #redPacket4, #redPacket5 {
  position: absolute;
  width: 50px;
  height: 50px;
  background-color: red;
  border-radius: 50%;
  animation: fall 2s linear infinite;
}

@keyframes fall {
  from {
    top: 0;
  }
  to {
    top: 100%;
  }
}

4. 控制红包雨效果

var redPacketRain = document.getElementById("redPacketRain");

var redPacket1 = document.getElementById("redPacket1");
var redPacket2 = document.getElementById("redPacket2");
var redPacket3 = document.getElementById("redPacket3");
var redPacket4 = document.getElementById("redPacket4");
var redPacket5 = document.getElementById("redPacket5");

redPacket1.style.left = "0px";
redPacket1.style.top = "0px";
redPacket2.style.left = "200px";
redPacket2.style.top = "0px";
redPacket3.style.left = "400px";
redPacket3.style.top = "0px";
redPacket4.style.left = "600px";
redPacket4.style.top = "0px";
redPacket5.style.left = "800px";
redPacket5.style.top = "0px";

setInterval(function() {
  redPacket1.style.left = Math.random() * 1000 + "px";
  redPacket1.style.top = Math.random() * 1000 + "px";
  redPacket2.style.left = Math.random() * 1000 + "px";
  redPacket2.style.top = Math.random() * 1000 + "px";
  redPacket3.style.left = Math.random() * 1000 + "px";
  redPacket3.style.top = Math.random() * 1000 + "px";
  redPacket4.style.left = Math.random() * 1000 + "px";
  redPacket4.style.top = Math.random() * 1000 + "px";
  redPacket5.style.left = Math.random() * 1000 + "px";
  redPacket5.style.top = Math.random() * 1000 + "px";
}, 100);
