html - ASP.Net MVC 控制标签栏

Question

我创建了一个新的 asp.net MVC 元素并开始根据我的需要对其进行修改。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;

 }

第一部分按照我的意愿更改了背景颜色。第二部分更改了除第一个选项卡(位于主页选项卡之前的选项卡)之外的文本颜色。同样对于确实发生变化的选项卡，我失去了悬停颜色。当我将鼠标悬停在它们上方时，它们会变成白色。现在只适用于第一个选项卡。

我想更改第一个选项卡的颜色并恢复所有选项卡的悬停颜色更改。

见附图。

Answer 1

问题是您正在使用 !important 标志。

我建议您创建自己的自定义类，例如 .navbar-custom。

改变:

<nav class="navbar navbar-inverse">

收件人:

<nav class="navbar navbar-custom">

下面是一个为您指明正确方向的示例:

/*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;
}
