html - 如何调整链接到悬停事件的动画？

问题描述

我有一个由指向其他网站的导航链接组成的标题，其中一些链接通过下拉菜单显示。通过事件悬停，我添加了一个动画和样式，以查看您每时每刻的状态，并且在下拉的情况下，会显示所有选项。问题是，一旦显示了下拉菜单，我就向内部链接添加了与主要链接相同的样式和动画，但在动画的情况下，我总是在同一个地方有下划线，而不是在每个链接下方. 提前感谢您的时间和帮助。我给你留下了一个例子的链接，因为我现在使用所描述的行为

解决方案

请将此添加到您的代码中

.dropdown-menu-link {
   padding-bottom:3px;
   position:relative;
}
.dropdown-menu-item {
   position:relative;
}

将代码更改 bottom:30%;为bottom: 0px;

.dropdown-menu-link:before {
    bottom: 0px;
}
