运用HTML5+CSS3和CSS滤镜做的精美的登录界面，无用到图片的
不少人为项目没有一个简洁和精美的登录页而烦恼，今天上班没多少事情做，在51cto里看了篇关于“使用html 5和css3制作登录页面完整步骤”的文章，我就动手做了一下，现在将代码贴出来，因为个人认为ie6在不久的将来必定被舍弃，所以这个登录页面的代码没有理会ie6里的情况。
代码如下：
1. <!doctype html>
2. <html>
3. <head>
4. <meta http-equiv="content-type" content="text/html; charset=gb2312">
5. <meta http-equiv="description" content="运用css3和css滤镜做的精美的登录界面，无用到图片的喔！">
6. <meta http-equiv="author" content="chenjinfei">
7. <meta http-equiv="date" content="2012-2-6">
8. <title>登录</title>
9. <link rel="stylesheet" href="style/common/common.css">
10. <style type="text/css">
