CSS 问题背景变黑

Question

在所附图片中，某些部分的背景为黑色，我无法弄清楚原因。

我知道我问的不是很具描述性，但如果有人能提出一些有用的建议，请多多指教

谢谢

下面的 Css(这是我聚焦黑色背景元素时从 firebug 得到的)

.curResults .tableTopControls {
    display: block;
    height: 30px;
    line-height: 30px;
    margin: 0 0 5px;
    width: 100%;
}

.tableTopControls {
    font-size: 11px;
    overflow: hidden;
}

Answer 1

在没有看到所有 css 和 html 的情况下很难做任何事情，但很有可能您没有为元素应用背景，并且父元素的背景颜色之一正在显示。

您发布的 css 中没有背景声明，所以这可能就是原因。我想发布您的整个(相关)代码或链接到演示会让您得到更准确的答案。
