Question

我正在学习如何写一个网站，但我有问题。我有一个带有下拉菜单的导航栏，我可以点击下拉菜单转到另一个页面但是没有下拉菜单的项目不能。例如我可以点击HTML CSS并转到该页面，但是如果我点击机器学习，我就无法做到。

这是我的导航栏代码和Css：

＆＃13;

ul {
list-style-type: none;
margin: 0;
padding: 0;
overflow: hidden;
background-color: #B3E5FC;}

li {
float: left;}

li a, .dropbtn {
display: inline-block;
color: black;
text-align: center;
padding: 14px 16px;
text-decoration: none;}

li a:hover, .dropdown:hover .dropbtn {
background-color: #6200EA;
color:white;}

li.dropdown {
display: inline-block;}

.dropdown-content {
display: none;
position: absolute;
background-color: #B3E5FC;
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;
text-align: left;}

.dropdown-content a:hover {background-color: #6200EA}
.dropdown:hover .dropdown-content {
   display: block;}
.ul {
     position: fixed;
     top: 20px0px;
     width: 100%;}
.active {
     background-color: #B3E5FC;
     color: Red;}

＆＃13;

<ul>
		    <li><a class="active" herf="index.html">Home</a></li>			
			<li class="dropdown">

                </div>

                <div class="dropdown-content">

                </div>
		    </li>
			</li>

＆＃13;

Answer 1

看起来你拼错了“href”为“herf”

<a herf="machine_learning.html">Machine Learning</a>

应该是

<a href="machine_learning.html">Machine Learning</a>

代替您的代码。您可以将此代码用于响应式导航栏。
