问题描述
我想知道如何改变'jumbotron'类的背景颜色，它在bootstrap.css中有一个默认的 background-color #eee 。
I want to know how to change the background-color of 'jumbotron' class, it has a default background-color #eee in bootstrap.css.
我试图通过擦除并赋予属性 none ， ，透明到我的自定义css仍然不工作。
I tried to override by erasing this and giving the attribute none,none !important, transparent into my custom css and still doesn't work.
我尝试检查浏览器窗口中的元素，并删除那里的属性，看看是否有任何更改，仍然是同样的问题。
I tried inspecting the element in the browser window and removing the property there to see if there was any change, it's still the same problem.
它将采用任何其他颜色，除了完全删除颜色。我问这个的原因是因为我有一个完整的背景图像，并希望jumbotron简单的透明，没有背景或颜色。除非，
It will adopt any other color, except removing the color entirely. The reason I'm asking this is because I have a full background image and want jumbotron to simply transparent with no background or color to it. Unless,
我从BootStrap 3.1.1文档中遗漏了一些我在那里检查过的东西。
I'm missing something from the BootStrap 3.1.1 documentation in which I checked there as well.
注意：我会使用jsfiddle.net轻松地显示你，但它不支持3.1.1，不知道如何实现引导。

推荐答案
只需从< html> 中删除类 full code>< body> 标记。然后为Jumbotron div设置样式 background-color：transparent！important; （如Amit Joki在他的答案中所述）。
Just remove class full from <html> and add it to <body> tag. Then set style background-color:transparent !important; for the Jumbotron div (as Amit Joki said in his answer).
