在侧边栏菜单上显示叠加打开

Question

我想在侧边栏菜单打开时显示叠加层。 并在点击叠加层时关闭菜单。

这就是我所做的：

 $(document).ready(function() {

    $('#menu-toggle').click(function(e) {
      e.preventDefault();
      $('#wrapper').toggleClass('toggled');
      $('#overlay').toggle();
    });

    $('#overlay').click(function() {
      $('#overlay').hide('200');
      $('#wrapper').removeClass('toggled');
    });
  });


#overlay {
  position: fixed;
  z-index: 999;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  display: none;
  background-color: rgba(0,0,0,.5);
}

我的代码工作正常。

我坚持让动画看起来很棒。请帮我修复动画效果。

我想要android棒棒糖，材料设计类型效果。

尝试下面的内容，

您可以使用jQuery fadeIn和fadeToggle函数

 $(document).ready(function() {

    $('#menu-toggle').click(function(e) {
      e.preventDefault();
      $('#wrapper').toggleClass('toggled');
      $('#overlay').fadeToggle( "slow", "swing" );
    });

    $('#overlay').click(function() {
      $('#overlay').fadeOut('slow');
      $('#wrapper').removeClass('toggled');
    });

  });
