Question

当有人将鼠标悬停在菜单标签上时，我已收到客户要求使菜单标签滑动的请求。

至于现在我有一个li.active roll和li：hover roll。

我不知道如何定义一个滚动条，在悬停非活动菜单选项卡时，活动的滚动条会相应地更改样式。

甚至可能吗？

HTML

<ul class="menu">
  <li><a href="#" class="active">Option1</a></li>
  <li><a href="#">Option2</a></li>
  <li><a href="#">Option3</a></li>
  <li><a href="#">Option4</a></li>
  <li class="slider"></li>
</ul>
