Question

我目前正在建立一个包含汉堡菜单的单页网站。该菜单是使用列表元素构建的，这些列表元素链接到该页面上的特定标记。

我只有一个问题，那就是将汉堡图标动画（在点击时变成十字架）恢复到正常状态。

以下是代码：

＆＃13;

$('#toggle').click(function() {
$(this).toggleClass('active');
$('#overlay').toggleClass('open').show();
});

$('#overlay li').on('click', function(){
$('#overlay').hide();
$('#toggle').removeClass("active");
});

  text-align: center;

  font-size: 20px;
  overflow: hidden;
  top: 5px;
}
.container a:after {

<div id="toggle" class="button_container">

            <li class="overlay-li"><a href="#">portfolio</a></li>
            <li><a href="#">services</a></li>
            <li><a href="#">about</a></li>

            </ul>
        </nav>
    </div>

有谁知道如何解决这个问题？

我没有超过50个声誉，因此无法在评论中解决您的问题，...

当你点击li时，你忘了切换'open'类叠加层所以只需在你的li点击功能中添加以下行

$('#overlay').toggleClass('open');

其他一切似乎都很好。：）
