Question

我重新格式化了现成的下拉菜单，并为其添加了一些线性动画，但我在某些元素的颜色方面存在问题：“Tab4_5”，“Tab3_3”，“Tab1_2”，“Tab1_3”

试试这个：

#nav li:nth-of-type(1) ul li a
{
  border-color: #636393;
}

#nav li:nth-of-type(2) ul li a, #nav li:nth-of-type(2) a {
 border-color: #B5222D;
}
#nav li:nth-of-type(3) ul li a, #nav li:nth-of-type(3) a  {
   border-color: #D4953C;
 }
#nav li:nth-of-type(4) ul li  a, #nav li:nth-of-type(4) a {
   border-color: #609491;
}
#nav li:nth-of-type(5) ul li  a, #nav li:nth-of-type(5) a {
 border-color: #87A248;
 }

#nav li:nth-of-type(1) ul li a:hover {
border-bottom: 35px solid #636393;
height: 9px;
 color: #fff;
 }

 #nav li:nth-of-type(2) ul li a:hover {
  border-bottom: 35px solid #B5222D;
   height: 9px;
  color: #fff;
  }
#nav li:nth-of-type(3) ul li a:hover {
    border-bottom: 35px solid #D4953C;
  height: 9px;
   color: #fff;
  }

#nav li:nth-of-type(4) ul li a:hover {
      border-bottom: 35px solid #609491;
     height: 9px;
     color: #fff;
