我想在我的网站底部放置一个联系表格，但表格底部被切掉了。你可以在这里看到一个 fiddle :

webform的代码如下:

CSS

div.box{
margin:0 auto;
width:500px;

border:1px solid #262626;
}

div.box h1{

text-transform:uppercase;
padding:5px 0 5px 5px;
border-bottom:1px solid #161712;
border-top:1px solid #161712; 
}

div.box label{
width:100%;
display: block;
background:#1C1C1C;
border-top:1px solid #262626;
border-bottom:1px solid #161712;
padding:10px 0 10px 0;
}
div.box label span{
display: block;
color:#bbb;
font-size:12px;

}

div.box .input_text{
padding:10px 10px;

border-right:1px double #333;
}

div.box .message{
padding:7px 7px;
width:350px;
background:#262626;
border-bottom: 1px double #171717;
border-top: 1px double #171717;
border-left:1px double #333;

overflow:hidden;
height:150px;
}

div.box .button
{
margin:0 0 10px 0;
padding:4px 7px;
background:#CC0000;
border:0px;
position: relative;
top:10px;

border-top: 1px double #660000;
border-left:1px double #FF0033;
border-right:1px double #FF0033;
}​

HTML

<form name="htmlform" method="post" action="html_form_send.php">
      <div class="box">
           <h1>Contact Form</h1>
                    <label>
                        <span>Full name *</span>
                        <input type="text" class="input_text" name="name" id="name"
                        />
                    </label>
                    <label>
                        <span>Email *</span>
                        <input type="text" class="input_text" name="email" id="email"
                        />
                    </label>
                    <label>
                        <span>Description of the product wanted *</span>
                        <input type="text" class="input_text"
                        name="subject" id="subject" />
                    </label>
                    <label>
                        <span>Estimated Quantity *</span>
                        <input type="text" class="input_text" name="quantity"
                        id="quantity" />
                        <input type="submit" class="button" value="Submit Form" />
                    </label>
                </div>

表单应该是这样的:

谁能解释一下为什么底部不见了，为什么表单标题的样式与应有的样式不同。

非常感谢任何帮助:)

#wrapper {

通常代码写得不好。学习如何编写好的 html 和 css。
