我想使用html&amp ;;进入我的网站横向下拉列表css,我不能这样做,我在列表和桌面上尝试它,但它没有工作。 有人可以给我这个代码或者教我如何做这个吗?
这是我的代码:
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
.dropdown-content a:hover {
background-color: #f1f1f1
}
.dropdown:hover .dropdown-content {
display: block;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41;
}

<ul>
<li class="lo" style="float:right"><a href="">try</a></li>
<li class="lo"><a href="">
<div class="dropdown">
<button class="dropbtn">Dropdown</button>
<div class="dropdown-content">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div></a></li>
<li class="lo"><a href="">try</a></li>
<li class="lo"><a href="">try</a></li>
<li class="lo"><a href="">try</a></li>
</ul>
