ASP.Net MVC控制标签栏

Question

我创建了一个新的asp.net MVC项目并开始根据我的需要进行修改。我在控制标签栏的颜色时遇到问题。我将这些更改添加到site.css文件

 .navbar-inverse 
{ background-color: lightblue !important;


}
.nav.navbar-nav li a {
   color: black !important;
   font-weight: bold !important;

 }

第一部分改变了我想要的背景颜色。第二部分更改了文本颜色，第一个选项卡除外，它位于主选项卡之前。此外，对于更改的选项卡，我丢失了悬停颜色。当我在它们上面盘旋时，它们常常变白。这仅适用于第一个选项卡。

我想更改第一个标签的颜色，还要恢复所有标签的悬停颜色更改。

见附图。

Answer 1

问题是您使用的是!important标志。

我建议您创建自己的自定义类，例如.navbar-custom。

变化：

<nav class="navbar navbar-inverse">

要：

<nav class="navbar navbar-custom">

以下是向您指出正确方向的示例：

＆＃13;

＆＃13;

/*Navbar styles*/

.navbar-custom {
  background-color: lightblue;
}
/*Navbar brand styles*/

.navbar-custom .navbar-brand {
  color: black;
}
/*Navbar brand hover styles*/

.navbar-custom .navbar-brand:hover,
.navbar-custom .navbar-brand:focus {
  color: blue;
}
/*Navbar anchor styles*/

.navbar-custom .nav.navbar-nav li a {
  color: black;
  font-weight: bold;
}
/*Navbar anchor hover styles*/

.navbar-custom .nav>li>a:focus,
.navbar-custom .nav>li>a:hover {
  background-color: #eee;
}
/* Mobile navbar toggle styles*/

.navbar-custom .navbar-toggle {
  border-color: #333;
}
.navbar-custom .navbar-toggle .icon-bar {
  background-color: #333;
}
