HTML动态粒子爱心代码是一种基于HTML、CSS和JavaScript技术实现的动态效果，它通过利用JavaScript粒子引擎技术，将一些彩色的小圆点组合成了一个可爱的爱心形状，让它随着鼠标的移动而动态地漂浮、旋转、变形等，非常具有观赏性。下面是一个HTML动态粒子爱心代码示例，你可以在浏览器中打开查看效果： ```html <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>HTML动态粒子爱心代码</title> <style> canvas { position: absolute; top: 0; left: 0; z-index: -1; } </style> </head> <body> <canvas id="canvas"></canvas> <script> var canvas = document.getElementById("canvas"); var ctx = canvas.getContext("2d"); canvas.width = window.innerWidth; canvas.height = window.innerHeight; var particles = []; for (var i = 0; i < 100; i++) { particles.push(new create_particle()); } function create_particle() { this.x = Math.random() * canvas.width; this.y = Math.random() * canvas.height; this.vx = Math.random() * 10 - 5; this.vy = Math.random() * 10 - 5; } function draw() { ctx.clearRect(0, 0, canvas.width, canvas.height); ctx.beginPath(); ctx.fillStyle = "red"; for (var i = 0; i < particles.length; i++) { var p = particles[i]; ctx.moveTo(p.x, p.y); ctx.arc(p.x, p.y, 5, 0, Math.PI * 2, true); p.x += p.vx; p.y += p.vy; if (p.x < -50) p.x = canvas.width + 50; if (p.y < -50) p.y = canvas.height + 50; if (p.x > canvas.width + 50) p.x = -50; if (p.y > canvas.height + 50) p.y = -50; } ctx.fill(); requestAnimationFrame(draw); } draw(); </script> </body> </html> ```
