制作步骤:

一, 引入prefixfree.js脚本

下面代码中使用了CSS3无前缀脚本prefixfree.js,可以省去CSS3中前缀“-moz”、“-webkit”、“-o”、“-ms”，如对该脚本不了解的可以点击下面链接哦:CSS3无前缀脚本prefixfree.js与Animatable使用介绍，不过使用上还是略有出入，自己认真看看哦。

<script type="text/javascript" charset="UTF-8" src="prefixfree.min.js"></script>

二, <body>标签结构

<body>       <div class="content">           <form action="" method="post" class="login-form">               <div class="username">                   <input type="text" name="username" placeholder="emma.watson@gmail.com" autocomplete="on" />                   <span class="user-icon icon">u</span>               </div>               <div class="password">                   <input type="password" name="password" placeholder="*******" />                   <span class="password-icon icon">p</span>               </div>               <div class="account-control">                   <input type="checkbox" name="Remember me" id="Remember me" value="Remember me" checked="checked" />                   <label for="Remember me" data-on="c" class="check"></label>                   <label for="Remember me" class="info">Remember me</label>                   <button type="submit">Login</button>               </div>               <p class="not-registered">Not a registered user yet?<a>Sign up now!</a></p>           </form>       </div></body>

三，CSS代码
