我想知道是否有人告诉我如何使用twitter bootstrap改变我的index.jsp页面的背景颜色？我尝试过更改正文背景颜色，但索引页面永远不会改变。它总是改变我创建的其他页面的颜色，我不知道为什么。如果有人可以告诉我如何将背景颜色改为BLACK，我将非常感激。谢谢:)）
我继续清理我的代码并从头开始重新尝试。我在这里发布了我的index.jsp和CSS代码供参考。
的index.jsp：

答案 0 :(得分：1)
您需要编写一个与该页面的body元素匹配的选择器，而不是其他页面。
目前，该body元素没有任何独特之处，因此您需要先更改HTML。
添加课程或ID。然后在你的选择器中使用它。
答案 1 :(得分：-2)
更改正文颜色
内联CSS的优先级高于外部CSS。
新：
<body style="background-color:#000000;">
此外，您可以使用!important来确定其优先级。
旧： BGCOLOR（已弃用）
<body bgcolor="#000000;">
