我创建了一个下拉菜单,我试图摆脱下拉开始时在父组件及其子组件之间获得的小空间,如下面的屏幕截图所示:
我希望下拉菜单从标签开始的位置开始,如下所示:
--------
| Parent
-----------
| Child
------------
请找到下面附带的代码段:
ul {
list-style-type: none;
margin: 0;
padding-left: 25px;
padding-right: 10px;
position: absolute;
}
li {
display: inline-block;
float: left;
margin-right: 1px;
}
li a {
display: block;
min-width: 138.7px;
height: 50px;
text-align: center;
line-height: 50px;
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
color: #fff;
background: #2f3036;
text-decoration: none;
padding-left: 10px;
padding-right: 10px;
}
li:hover a {
background: green;
}
li:hover ul a {
background: grey;
color: #2f3036;
height: 40px;
line-height: 40px;
text-align: center;
}
li:hover ul a:hover {
background: green;
color: #fff;
}
li ul {
display: none;
}
li ul li {
display: block;
float: none;
}
li ul li a {
width: auto;
min-width: 100px;
}
ul li a:hover+.hidden,
.hidden:hover {
display: block;
width: auto;
}
#menu {
text-align: center;
}
<ul class="menu">
<li><a href="#">Somthing</a></li>
<li> <a href="#">something</a>
<ul class="hidden">
<li><a href="#">somethoing</a></li>
<li><a href="#">something</a></li>
</ul>
</li>
</ul>
提前致谢。

在隐藏的类上将填充设置为0。 .hidden{padding: 0;}
并删除li ul li a{width:auto; min-width:100px;}
