我创建了一个简单的.arrow-up
CSS类:
.arrow-up {
width: 0;
height: 0;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
border-bottom: 5px solid black;
}
我希望此箭头位于第二级菜单的正确顶部,这是我的菜单代码:
HTML:
<header>
<div class="welcome_area">
<p>
Welcome, <b><a href="profile.php">Arkam Gadet</a> </b>
</p>
</div>
<div class="menu">
<nav>
<ul>
<li><a href="profile.php">My Profile</a>
<ul>
<li><a href="#">My Questions</a>
</li>
<li><a href="#">Settings</a>
</li>
</ul>
</li>
<li><a href="inbox.php">Inbox</a>
</li>
<li><a href="#">Notifications</a>
</li>
</ul>
</nav>
</div>
</header>
CSS:
header {
background-color: #eee;
height: 45px;
box-shadow: 0px 2px 3px 1px #bbb;
}
a {
color: black;
text-decoration: none;
}
h2 {
color: #f79a1d;
}
.welcome_area {
float: left;
margin-left: 5%;
}
.menu {
float: right;
margin-right: 5%;
}
.menu nav > ul {
position: relative;
padding:0px;
}
.menu nav ul li {
display: inline;
padding: 5px;
}
.menu nav ul li a {
padding: 2px;
}
.menu nav ul li a:hover {
background: #eee;
border: 0;
border-radius: 3px;
box-shadow: 0px 0px 2px 1px #000;
}
.menu nav > ul ul {
position: absolute;
left: -30px;
top: 40px;
padding:0px;
width: 150px;
border-radius: 3px;
display: none;
background-color: #eee;
box-shadow: 0px 0px 2px 3px #bbb;
}
.menu nav > ul li > ul li {
display: block;
}
我试图将它添加为列表中的li但是它不会在它内部进入它。
如何将.arrow-up
置于第二级菜单之上?
答案 0 :(得分:0)
这些方面的内容如何:
.menu nav ul ul:before {
width:0;
height: 0;
border-left: 5px solid transparent;
border-right: 5px solid transparent;
display:block;
clear:both;
position:absolute;
top:-5px;
border-bottom: 5px solid black;
content:'' ;
}
