在侧边栏菜单上显示叠加层打开

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。

这里是我做了什么：

$(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); 
} 

这里是演示 - https://jsbin.com/vasisedoha/edit?css,js,output

我的代码是工作的罚款。

我被困在使动画看起来不错。请帮我修复动画效果。

我想要android棒棒糖，材质设计类效果。

请尝试以下方法，

您可以使用jQuery fadeIn和fadeToggle功能

$(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'); 
 
    }); 
 

 
    });
