有人用html就写了一朵漂亮的玫瑰，是不是有点太骚气了。纯javascipt就弄出了玫瑰花，再次显示了HTML5的威力
警告：传说IE6内核是无法看到的，建议用Chrome或者Firefox。
玫瑰花效果：
实现代码：
复制代码代码如下:
<!doctype html>
<html>
<head>
<title>Love</title>
<meta charset="utf-8" />
<!--[if IE]>
<script src="/UploadFiles/2021-03-30/html5.js"><![endif]-->
</head>
<body>
<canvas id="c"></canvas>
<script>
var b = document.body;
var c = document.getElementsByTagName('canvas')[0];
var a = c.getContext('2d');
document.body.clientWidth;
</script>
