本文主要是介绍用HTML5实现灯笼效果，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
本文介绍了两种实现效果：一种使用画布（canvas）标签/元素，另一种不用画布（canvas）标签/元素主要使用CSS实现。
使用画布（canvas）标签/元素实现，下面，在画布上，用JavaScript画两个红灯笼，并且红灯笼左右来回移动的源码：
<!DOCTYPE html>
<html>
<head><title>红灯笼</title><style>canvas {border: 1px solid black;background-color: blue; /*设置画布的背景色为蓝色*/}</style>
</head>
<body>
<!-- 设置画布宽高是500*300，单位是 px。 --><canvas id="canvas" width="500" height="300"></canvas><script>var canvas = document.getElementById('canvas');var context = canvas.getContext('2d');var angle1 = 0;var angle2 = 0; // 使第二个灯笼的初始角度与第一个灯笼不同function drawLantern(x, y, radius, angle) {x += Math.sin(angle) * 20;// Draw the suspension linecontext.beginPath();context.moveTo(x, y - radius / 4);context.lineTo(x, 0);context.stroke();// Draw the top context.beginPath();context.arc(x, y, radius / 4, 0, Math.PI * 2);context.fillStyle = 'gold';context.fill();context.stroke();// Draw the main bodycontext.beginPath();context.arc(x, y, radius, 0, Math.PI * 2);context.fillStyle = 'red';context.fill();context.stroke();// Draw the bottomcontext.beginPath();context.arc(x, y + radius / 2, radius / 4, 0, Math.PI * 2);context.fillStyle = 'gold';context.fill();context.stroke();// Draw the tasselcontext.beginPath();context.moveTo(x, y + radius / 2);context.lineTo(x, y + radius * 1.2);context.moveTo(x - radius / 6, y + radius / 2);context.lineTo(x - radius / 6, y + radius * 1.2);context.moveTo(x + radius / 6, y + radius / 2);context.lineTo(x + radius / 6, y + radius * 1.2);context.stroke();}function animate() {context.clearRect(0, 0, canvas.width, canvas.height);context.fillStyle = 'blue';context.fillRect(0, 0, canvas.width, canvas.height);drawLantern(200, 200, 50, angle1);drawLantern(300, 200, 50, angle2);angle1 += 0.05;angle2 += 0.05;requestAnimationFrame(animate);}animate();</script>
</body>
</html>
运行效果如下：
下面是另一种实现主要使用CSS实现，源码如下：
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>红灯笼效果</title><!-- 灯笼代码↓，放在 head标签内-->
