将底部边框添加到悬停/焦点/活动bootstrap wordpress导航菜单项

时间：2016-06-15 19:56:50

标签： css wordpress twitter-bootstrap menu

我想在我的菜单导航按钮上添加边框底部，该按钮悬停在上面，或者已选中，或者是当前菜单项。我不想只是想添加一个“文字装饰：下划线”，我想有一个3px高的边框，只有它上面的导航项的宽度，我找不到适用的例子 - 任何帮助非常感谢：

我正在使用wordpress动态菜单：

<div class="collapse navbar-collapse navbar-ex1-collapse">
   <ul id="menu-main-menu" class="nav navbar-nav">
     <li id="menu-item-32" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-6 current_page_item menu-item-32 active">
     <li id="menu-item-31" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-31">
     <li id="menu-item-30" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-30">
     <li id="menu-item-29" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-29">
     <li id="menu-item-26" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-has-children menu-item-26 dropdown">
     <li id="menu-item-25" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-25">
     <li id="menu-item-498" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-498">
     <li id="menu-item-499" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-499">
</ul>
</div>

如何使边框的宽度等于其上方文本的宽度

您可以将每个链接的文字包装到<span></span>并将the box-shadow property应用于此span。

在您的网站上

UPD。我添加了下拉菜单的代码。

我根据您的网站制作了a Minimal, Complete, and Verifiable example。您必须将每个链接的文本包装到<span></span>并添加此CSS以解决您的问题：

.dropdown-toggle {
  margin-top: 0;
}
#menu-main-menu .current-menu-item a,
.nav > li > a:focus,
.nav > li > a:hover {
  box-shadow: none;
}
@media (min-width: 768px) {
  .navbar-nav > li > a {
    padding: 0 10px;
  }
  .navbar-nav > li > a > .fa-fw {
    width: auto;
  }
  .navbar-nav > li > a > .fa-fw,
  .navbar-nav > li > a > span {
    display: inline-block;
    padding: 15px 0;
  }
  .navbar-nav > li > a:hover > span,
  .navbar-nav > li > a:focus > span,
  .navbar-nav > .active > a  > span {
    box-shadow: inset 0px -3px 0px #f2ab00;
  }
}

对于Bootstrap导航栏

我使用了span:first-child选择器，因为某些链接可能包含<span class="sr-only"></span>。

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');

.navbar-nav > li > a:focus > span:first-child,
.navbar-nav > .active > a  > span:first-child {

}

@media (min-width: 768px) {
  .navbar {
    border: none;
  }
  .navbar-nav > li > a {
    padding: 0 15px;
  }
  .navbar-nav > li > a > span:first-child {
    display: inline-block;
    padding: 15px 0;
  }
  .navbar-nav > li > a:hover > span:first-child,
  .navbar-nav > li > a:focus > span:first-child,
  .navbar-nav > .active > a  > span:first-child {
