如何删除锚元素上的突出显示？

Question

我在<ul>元素中生成了此html元素锚。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<ul class="nav pull-left">             
    <li style="display: inline-block;text-align: center;"><a class="" ui-sref="sites.list"><i class="glyphicon glyphicon-tree-conifer"></i> <br>sites</a></li>
    <li style="display: inline-block;text-align: center;"><a class="" ui-sref="sitesDamages.sitesList"><i class="glyphicon glyphicon-exclamation-sign"></i> <br>events</a></li>         
</ul>

当我在链接上导航鼠标时，它突出显示。

知道如何删除高光吗？

Bootstrap的CSS规则之一是：

.nav > li > a:focus, .nav > li > a:hover {
    text-decoration: none;
    background-color: #eee;
}

只需使用您自己的更具体的规则覆盖它：

.nav.pull-left>li>a:focus, .nav.pull-left>li>a:hover {
  background-color: transparent;
}

例：

.nav > li > a:focus, .nav > li > a:hover {
    text-decoration: none;
    background-color: #eee;
}

.nav.pull-left>li>a:focus, .nav.pull-left>li>a:hover {
  background-color: transparent;
}
