好的,以下是一个简单的HTML5动态爱心烟花表白页面的代码:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>动态爱心烟花表白</title>
<style>
body {
background-color: black;
text-align: center;
color: white;
}
canvas {
position: absolute;
z-index: -1;
}
</style>
</head>
<body>
<h1>我喜欢你,你愿意做我的女朋友吗?</h1>
<canvas id="canvas"></canvas>
<script>
var canvas = document.getElementById('canvas');
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
var ctx = canvas.getContext('2d');
// 创建烟花
function createFirework() {
var firework = {};
firework.x = canvas.width / 2;
firework.y = canvas.height;
firework.color = getRandomColor();
firework.particles = [];
// 生成烟花粒子
for (var i = 0; i < 50; i++) {
var particle = {};
particle.x = firework.x;
particle.y = firework.y;
particle.color = firework.color;
particle.radius = Math.random() * 5 + 1;
particle.vx = Math.random() * 10 - 5;
particle.vy = Math.random() * 10 - 5;
particle.gravity = 0.2;
firework.particles.push(particle);
}
// 将烟花粒子添加到数组中
fireworks.push(firework);
setTimeout(function() {
fireworks.splice(fireworks.indexOf(firework), 1);
}, 3000); // 3秒后删除烟花
}
// 获取随机颜色
function getRandomColor() {
var letters = '0123456789ABCDEF';
var color = '#';
for (var i = 0; i < 6; i++) {
color += letters[Math.floor(Math.random() * 16)];
}
return color;
}
// 绘制烟花
function drawFirework(firework) {
for (var i = 0; i < firework.particles.length; i++) {
var particle = firework.particles[i];
ctx.beginPath();
ctx.arc(particle.x, particle.y, particle.radius, 0, Math.PI * 2);
ctx.fillStyle = particle.color;
ctx.fill();
particle.vx += Math.random() * 0.2 - 0.1;
particle.vy += particle.gravity;
particle.x += particle.vx;
particle.y += particle.vy;
}
}
// 动画循环
function loop() {
ctx.clearRect(0, 0, canvas.width, canvas.height);
if (Math.random() < 0.1) {
createFirework();
}
for (var i = 0; i < fireworks.length; i++) {
drawFirework(fireworks[i]);
}
requestAnimationFrame(loop);
}
var fireworks = [];
loop();
</script>
</body>
</html>
```
这个页面会在黑色背景上生成多个随机颜色的爱心烟花,同时上面有一句简单的表白。当用户打开这个页面时,会看到动态的爱心烟花效果,非常浪漫。
