我正在使用Nathan Smith Grid System，我用“container_12”类包装的所有内容都有白色背景。我想要的是透明。
示例： http://jsfiddle.net/JordanSimps/RZvxn/1/
HTML：
<!-- Beginning of the blue top header -->
<div class="top-header-wrap">
<div class="container_12">
<div class="top-header">
<div class="grid_2">
<img class="hover" src="http://www.dubstepcast.com/images/phone.png" /> (586) 997-9490
</div>
<div class="grid_3">
<img src="http://www.dubstepcast.com/images/mail.png" /> <a href="mailto:jordansimps@me.com" alt="E-Mail us">info@experienceheritage.org</a>
</div>
<div id="social">
<div class="grid_7">
<ul>
<li id="twitter"><a href="1.html"><img id="twitter" src="http://www.dubstepcast.com/images/twitter.png" /></a></li>
<li id="pinterest"><a href="1.html"><img id="pinterest" src="http://www.dubstepcast.com/images/pinterest.png" /></a></li>

</ul>
</div>
</div>
</div>
</div>
</div>
<!-- End of the blue top header -->
<!-- Beginning of the second header - Logo & Navigation buttons -->
<div class="container_12">
<div class="bottom-header">
<!-- LOGO BEGINS HERE -->
<div class="grid_2">

答案 0 :(得分：2)
根据您的jsfiddle，以下CSS规则将应用于demo.css文件中的container_12
.container_12, .container_16, .container_24 {
background-color: #fff; /* Makes the background white */
background-repeat: repeat-y;
margin-bottom: 20px;
}
所以你可以删除这些或用
覆盖它们.container_12 {
background: none
}
答案 1 :(得分：0)
将其添加到css
.container_12{
background: transparent;
}
答案 2 :(得分：0)
你有背景色：#fff;在demo.css中设置
将其更改为background-color：transparent;
答案 3 :(得分：0)
根据firebug，这是demo.css的第2行
.container_12, .container_16, .container_24 {
background-color: #FFFFFF;
background-repeat: repeat-y;
margin-bottom: 20px;
}
所以使用
#div.container_12 {
background-color: transparent;
}
以更高的特异性覆盖它
