新年快乐代码特效是一种通过HTML、CSS和JavaScript实现的动态效果,用于在网页上展示新年祝福。下面是一个简单的示例代码:
```html
<!DOCTYPE html>
<html>
<head>
<title>新年快乐</title>
<style>
body {
background-color: black;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}
.fireworks {
position: relative;
width: 300px;
height: 300px;
}
.firework {
position: absolute;
width: 10px;
height: 10px;
background-color: #f00;
border-radius: 50%;
animation: explode 1s infinite;
}
@keyframes explode {
0% {
opacity: 1;
transform: scale(1);
}
100% {
opacity: 0;
transform: scale(2);
}
}
</style>
</head>
<body>
<div class="fireworks">
<div class="firework"></div>
</div>
<script>
function createFirework() {
const firework = document.createElement('div');
firework.className = 'firework';
firework.style.left = Math.random() * 280 + 'px';
firework.style.top = Math.random() * 280 + 'px';
document.querySelector('.fireworks').appendChild(firework);
}
setInterval(createFirework, 200);
</script>
</body>
</html>
```
这段代码会在网页上显示一个黑色背景,中间有一个300x300像素的区域,不断产生随机位置的小圆点,模拟烟花爆炸的效果。
