javascript - 如何使纯 CSS 下拉菜单与其中的两个可重定向链接一起工作？

Question

我已经创建了一个下拉联系人菜单，其中包含 2 个链接。但似乎当我点击联系按钮，然后点击所需的链接时，它只会关闭下拉菜单，而不会将用户重定向到任何地方。我在某处读到这是因为另一个鼠标按下事件会触发 :focus 基本上没有焦点？我怎样才能使这个菜单工作？我只知道一点点javascript。
下面的 HTML -

<div class="contact">
            <button class="contactbtn">Contact</button>
            <ul>
               <li>
                  <p>For Any Enquiries→</p>
               </li>
               <li><a id="mail" href="mailto:hello@shekleung.com">hello@shekleung.com</a></li>
               <li>+44 7463 070158</li><br>

            </ul>
         </div>

Answer 1

那是因为你设置了pointer-events: none对于无序列表。这会影响它的 child <li>以及。

.contact ul,
.contact-a ul {
   position: absolute;
   left: -10vw;
   margin-top: 20px;
   width: 300px;
   height: 150px;
   font-size: 1.5rem;
   font-weight: bold;
   display: flex;
   flex-direction: column;
   justify-content: space-around;
   align-items: flex-end;
   list-style: none;
   text-transform: uppercase;
   font-size: 1rem;
   opacity: 0;
   pointer-events: none;  <<<<<<<<<<<<<<<<<<<<  cause of problem
   transform: translateY(-10px);
   transition: all 0.4s ease;
}

最好去掉那个。
