html - 为什么我的容器显示白色背景？

Question

我使用的是Nathan Smith Grid System，我用“container_12”类包装的所有东西都有白色背景。我想要的是它是透明的。

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">

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覆盖它们

.container_12 {
    background: none
}

你有背景颜色：#fff; 在 demo.css 中设置

将其更改为背景颜色：透明；

根据萤火虫，这是 demo.css 的第 2 行

.container_12, .container_16, .container_24 {
    background-color: #FFFFFF;
    background-repeat: repeat-y;
    margin-bottom: 20px;
}

所以用

#div.container_12 {
    background-color: transparent;
}

以更具体的方式覆盖它
