css - 如何显示与其他元素颜色不同的面包屑元素

Question

我有这个 css 和 html 的面包屑，但我不想要悬停状态。相反，我希望能够在 <li> 中显示一项与其他颜色不同。我尝试使用不同背景的不同类(class)，但我失败了。

有人知道怎么做吗？

谢谢!!

我只是更改了 :hover分入color允许您添加 class="color"到 <li> 之一的

body {
  font-family: Arial, Helvetica, sans-serif;
}
#crumbs ul li a {
  display: block;
  float: left;
  height: 15px;
  background: #999;
  text-align: center;
  padding: 20px 30px 0 20px;
  position: relative;
  margin: 0 10px 0 0;
  font-size: 18px;
  text-decoration: none;
  color: #fff;
  line-height: 1px;
  cursor: default;
}
#crumbs ul li a:after {
  content: "";
  position: absolute;
  right: -17px;
  top: 0;
  border-top: 17px solid transparent;
  border-bottom: 17px solid transparent;
  border-left: 17px solid #999;
  z-index: 1;
}
#crumbs ul li a:before {
  content: "";
  border-top: 17px solid transparent;
  border-bottom: 17px solid transparent;
  border-left: 17px solid #fff;
  position: absolute;
  left: 0;
  top: 0;
}
#crumbs ul li {
  display: inline;
}
#crumbs ul li a.color {
  background: #779519;
}
#crumbs ul li a.color:after {
  border-left-color: #779519;
}
#crumbs ul li:first-child a {
  border-top-left: 10px;
  border-bottom-left: 10px;
}
#crumbs ul li:first-child a:before {
  display: none;
}
#crumbs ul li:last-child a {
  padding-right: 80px;
  border-top-right: 10px;
  border-bottom-right: 10px;
}
#crumbs ul li:last-child a:after {
  display: none;
}

<div id="crumbs">
  <ul>
    <li><a href="#">Tipo de Bilhete / Zona</a>
    </li>
    <li><a href="#" class="color">Sector</a>
    </li>
    <li><a href="#">Lugar</a>
    </li>
  </ul>
</div>
