在悬停UL菜单时，从左向右滑动边框

时间：2016-10-19 08:37:11

标签： html css border

我希望此边框从左向右滑动（仅限dropmenus）。但无法弄清楚

这是我到目前为止的方式，我不再有任何想法。

菜单是用ul和li-s构建的。

这可能吗？

谢谢，

我在下面添加了10行css：你在找这个：

.toggle,
[id^=drop] {
	display: none;
}
.toggle_menu,
[id^=drop] {
	display: none;
}
nav:after {
	content:"";
	display:table;
	clear:both;
}
nav ul {
	padding:0;
	margin:0;
	list-style: none;
	position: relative;
	}
nav ul li.active_link a{
	font-size:14px;
	text-decoration:none;
	font-family: 'Lato';
	font-weight:600;
}
nav ul li {
	margin: 0px;
	display:inline-block;
	float: left;
	background-color: white;
	}
nav a {
	display:block;
	    padding: 14px 16px;
	color:#FFF;
	font-size:14px;
	text-decoration:none;
	color:black;
	font-family: 'Lato';
	font-weight:400;
}

nav ul li ul li:hover { /*background: #000000; */}
nav a:hover { 
	/*background-color: #000000;*/ 
}
nav ul li ul{
	display: none;
	position: absolute;
	  color: #31302B;
    background: #FFF;
    cursor: pointer;
    box-shadow: inset 0 0 0 0 #b6945d;
	-webkit-transition: all ease 1s;
	-moz-transition: all ease 1s;
	transition: all ease 1s;
}
nav ul li:hover > ul{
    box-shadow: inset 900px 0px 0px #b6945d;
    color: #fff;
}
nav ul li:hover > ul {
	display:inherit;
}

    display: list-item;
    position: relative;
}
nav ul ul ul li {

}
nav ul li ul:hover:after { 
  width: 100%; 
}
<nav>
        <label for="drop" class="toggle_menu"><img src="assets/images/mobile_button.png"></label>
