Hide a div with transition

Question

I have a menu for mobile which takes all screen and I want to hide and display it with a fade transition.

The problem is that I used the opacity to do this effect and when the opacity is set to 0 the links are invisible but they are still clickable, I tried to resolve this with z-index or display but the result of the transition isn't the same.

Do you know how can I do ?

Here is a fiddle of my code

$(window).ready(function() {
  //MENU MOBILE
   $('#menu-switch').click(function() {
   $( this ).toggleClass('switch-on');
   $('#menu-mobile').toggleClass('animated');
});
});    

.content{
    height:100vh;
    width:100vw;
}
.cmn-toggle-switch {
  z-index: 999;
  display: block;
  position: fixed;
  top:0;
  left:0;
  overflow: hidden;
  margin: 0;
  padding: 0;
  width: 60px;
  height: 50px;
  font-size: 0;
  text-indent: -9999px;
  box-shadow: none;
  border-radius:0;
  border: none;
  cursor: pointer;
  background:transparent;
  
}
.cmn-toggle-switch:focus {
  outline: none;
}
.cmn-toggle-switch span {
  display: block;
  position: absolute;
  top: 20px;
  left: 10px;
  right: 10px;
  height: 5px;
  border-radius: 15px;
  background: black;

Answer 1

You should use also visibility: hidden in your transition, because events still work with opacity: 0 (read more here).

JSFiddle:

$(window).ready(function() {
  //MENU MOBILE
   $('#menu-switch').click(function() {
   $( this ).toggleClass('switch-on');
   $('#menu-mobile').toggleClass('animated');
});
});

.content{
    height:100vh;
    width:100vw;
}
.cmn-toggle-switch {
  z-index: 999;
  display: block;
  position: fixed;
  top:0;
  left:0;
  overflow: hidden;
  margin: 0;
  padding: 0;
  width: 60px;
  height: 50px;
  font-size: 0;
  text-indent: -9999px;
  box-shadow: none;
  border-radius:0;
  border: none;
  cursor: pointer;
  background:transparent;
  
}
.cmn-toggle-switch:focus {
  outline: none;
}
.cmn-toggle-switch span {
  display: block;
  position: absolute;
  top: 20px;
  left: 10px;
  right: 10px;
  height: 5px;
  border-radius: 15px;
  background: black;
    -webkit-transition: all 400ms cubic-bezier(0.645, 0.045, 0.355, 1.000); 
   -moz-transition: all 400ms cubic-bezier(0.645, 0.045, 0.355, 1.000); 
     -o-transition: all 400ms cubic-bezier(0.645, 0.045, 0.355, 1.000); 
        transition: all 400ms cubic-bezier(0.645, 0.045, 0.355, 1.000);
}

.cmn-toggle-switch span::before,

Answer 2

You could use keyframes and animate out the opacity followed by the width or height. Fiddle here https://jsfiddle.net/otvpL8xp/4/

@-moz-keyframes hideMenu {
    0% {
        opacity:1;
    }
    100% {
        opacity: 0;
    }
}
@-moz-keyframes widthMenu {
    0% {
        width:100%;
    }
    100% {
        width: 0;
    }
}
div#menu-mobile.animated {
    animation: hideMenu .4s ease forwards, 
                widthMenu 0s .5s forwards;
}

Answer 3

You can change max-height to 0 and hide overflow. It's only one of passible solutions.

div#menu-mobile.animated{
    opacity:0;
    max-height: 0;
    overflow: hidden;
}
