我正在使用 twitter bootstrap 构建一个 wordpress 网站（http://www.graditudemedia.com/），并在页脚中放置了一个联系表。当视口宽度大于 1215 像素时，它看起来很好，但列在其下方重叠。它不需要响应，所以我尝试删除 bootstrap-responsive.css 并且只会使列重叠而不管视口大小。一种菜鸟，任何帮助将不胜感激。这是表单代码：
<div id="contact">
<div class="container">
<div class="row">
<div class="span12 center">
<h2>Contact Us</h2>
</div>
</div>
<div class="row">
<div class="12 center">
<p>It’s about time you did something awesome with your brand. Let’s get started.<p>
<p> </p>
</div>

<div class="row">
