我做了「漢堡包」菜單,反應靈敏的風格,這將覆蓋該頁面的瀏覽器是在一個菜單。製作漢堡包菜單淡出工作

我把所有的HTML/CSS想通了,但我想補充淡入淡出效果。

淡入與jquery代碼一起工作,但菜單沒有淡出。已經嘗試了一些在SO上的想法,但都沒有成功。

任何幫助? 小提琴https://jsfiddle.net/f19kz640/

#nav-icon.open span:nth-child(4) {

} 

使用Javascript/JQuery的

$(document).ready(function(){ 
    $('#nav-icon').click(function(){ 
     $(this).toggleClass('open'); 
     if($('#menu').css('opacity') == '0'){ 
     $('#menu').css('opacity','1'); 
     $('#menu').fadeIn(300).css('display','table'); 
     }else{ 
     $('#menu').css('opacity','0'); 
     $('#menu').fadeOut(300).css('display','none'); 
     } 
    }); 
});

你可以容易事情簡化了很多:

$(document).ready(function(){ 
    $('#nav-icon').click(function(){ 
     $(this).toggleClass('open'); 
     $('#menu').fadeToggle(300); 
    }); 
}); 

Updated Fiddle

沒有理由不透明度性能或顯示性能的發揮,這是jQuery的fade()功能的一部分,您只需切換即可。

驚人。我注意到我的代碼不是最好的任務,但我不認爲使用fadetoggle。 – uniqezorpt
