Question

我正在尝试更改Visual Studio 2013中新的ASP.NET MVC 5应用程序附带的默认主题中的简单CSS属性。特别是我需要更改导航菜单的背景颜色。

我通过Firebug找到了这个属性，它的新值应该是：

.navbar-inverse { background-color: #5B80A5}

我最初尝试在Site.css中添加覆盖CSS行，因为我注意到BundleConfig.cs中的这些行：

    bundles.Add(new StyleBundle("~/Content/css").Include(
              "~/Content/bootstrap.css",
              "~/Content/site.css"));

然而，导航菜单的背景颜色没有变化。

然后我在我的解决方案中搜索了.navbar-inverse并返回了搜索结果：

Web\Content\bootstrap-theme.css(249):.navbar-inverse .navbar-nav > .active > a {

我在每个上述文件的末尾添加了自定义CSS行，但仍然没有发生任何事情。我每次重建项目，清除浏览器中的缓存，但没有任何改变。

有关如何覆盖默认FPrap样式的任何想法吗？它让我疯了！

类似的问题并没有真正帮助：

Answer 1

文件名无效 - 请使用＆＃34; Site.css＆＃34;不是＆＃34; site.css＆＃34;。我也有这个问题，并且没有任何其他改变就这样解决了......

bundles.Add(new StyleBundle("~/Content/css").Include(
          "~/Content/bootstrap.css",
          "~/Content/Site.css"));

Answer 2

使您的自定义类包含.navbar-inverse类的样式比bootstrap的类更具体。您可以在<body>标记中添加一个类，并使用该类作为自定义替代的前缀。

.myCustomStyle .navbar-inverse

如果您无法编辑HTML，则可以使用每个html文档都有的明显标记：

body .navbar-inverse

还会使您的样式更具体，但对于代码可读性而言，请使用第一种方法。

您不必担心文件的放置位置，因为CSS特异性将始终覆盖bootstraps类+您始终可以确定它是您的类的名称前缀，使进一步调试更容易。

Answer 3

_layout.cshtml CSS order

如果将 CSS 引用放在引导程序之前，它将使自定义 CSS 优先于引导程序。如果你看我在 bootstrap.min.css 引用上面有 site.css 引用。这是在 Shared/_Layout.cshtml 文件中。

Answer 4

删除bootstrap.min.css或bootstrap.css。类似的问题在这里 CSS changes on MVC App not working
