CSS Animation for panel sliding Animation not working

While rewriting entirely my UI, simplifying a lot of the old markup (and thus the JavaScript that powers it up) I've found a problem I can't fix.

One of the many components is a panel that slides above another. I've extracted that part as follows:



$( '#preview' ).addClass( 'open' )

$( '#preview .navigation .open-panel .fa' ).on( 'click', function() {
$( '#inner' ).removeClass( 'open' ).addClass( 'open' );
});

$( '#inner .navigation .close-panel .fa' ).on( 'click', function() {
$( '#inner' ).addClass( 'closed' ).removeClass( 'open' )
});

body {
height: 80vh;
margin: 10vh !important;
}

#preview {
align-items: center;
border-radius: 0.7vw;
/*bottom: 0;*/
display: none;
height: 80vh; /** 91.6vh */
/*left: 0;*/
/*margin: auto;*/
position: absolute;
overflow: hidden;
/*right: 0;*/
/*top: 0;*/
width: 31.3vw;
/*z-index: 4;*/

background-color: blue;
}

#preview.open {
animation-name: fadeIn;
animation-duration: 400ms;
animation-fill-mode: both;

display: -webkit-box; /* OLD - iOS 6-, Safari 3.1-6 */
display: -moz-box; /* OLD - Firefox 19- (buggy but mostly works) */
display: -ms-flexbox; /* TWEENER - IE 10 */
display: -webkit-flex; /* NEW - Chrome */
display: flex;
}

#preview .navigation {
position: absolute;
/*z-index: 7;*/
}

#preview .navigation .open-panel {
background-color: #FFF;
border: 1px solid #000;
border-left: none !important;
border-bottom-right-radius: 0.5vw;
border-top-right-radius: 0.5vw;
}

#preview .navigation .open-panel .fa {
cursor: pointer;
font-size: 6vh;
margin: 2.1vh 0.25vw 1.45vh 0.4vw;
}

#inner {
align-items: center;
/*bottom: 0;*/

display: -webkit-box; /* OLD - iOS 6-, Safari 3.1-6 */
display: -moz-box; /* OLD - Firefox 19- (buggy but mostly works) */
display: -ms-flexbox; /* TWEENER - IE 10 */
display: -webkit-flex; /* NEW - Chrome */
display: flex;

height: 80vh;
left: -62.6vw; /** 2x `#preview` width, but negative */
/*margin: auto;*/
position: absolute;
overflow: hidden;
/*right: 0;*/
/*top: 0;*/
width: 31.3vw;
/*z-index: 8;*/

background-color: red;
}

#inner.open {
animation-name: slideInLeft;
animation-duration: 1s;
animation-fill-mode: both;
left: 0;
}

#inner.closed {
animation-name: slideInRight;
animation-duration: 1s;
animation-fill-mode: both;
left: -62.6vw;
}

#inner .navigation {
right: 0 !important;
/*z-index: 9;*/
}

#inner .navigation .close-panel {
background-color: #FFF;
border: 1px solid #000;
border-right: none !important;
border-bottom-left-radius: 0.5vw;
border-top-left-radius: 0.5vw;
}

#inner .close-panel .fa {
cursor: pointer;
font-size: 6vh;
margin: 2.1vh 0.4vw 1.45vh 0.25vw;
}

For some reason the clicking action doesn't work twice. In my UI it works fine ;)


The old UI was extremely complex for such little thing. In this rewriting I decided to take advantage of CSS Animations (blowing away compatibility wit old IEs) and the Daneden's Animate.css

The JavaScript just adds/removes certain classes to trigger the animations. For the opening it works fine, but for the closing it's pretty much ignored.

What could that be?

Side notes

As you can see there's a lot of rules commented.

I've kept them to show some of the real values of my code (widths, heights, z-indexes...) and some are reminiscences of an old attempt of box centering without Flexbox.

The Flexbox vendor prefixes are to make Firefox understand Flexbox (it was ignoring
display: flex
) o.O

Answer Source

I changed these two lines.
$( '#inner' ).removeClass( 'open' ).addClass( 'open' );
$( '#inner' ).addClass( 'closed' ).removeClass( 'open' );
to this
$( '#inner' ).addClass( 'open' );
$( '#inner' ).removeClass( 'open' );

EDIT:
The closing animation should now work properly.
It will remove the class closed when it opens $( '#inner' ).removeClass( 'closed' );.
It will add class closed when it closes. $( '#inner' ).addClass( 'closed' );
And use animation-name: slideOutLeft; for #inner.closed and everything will work properly!

$( '#preview' ).addClass( 'open' );

$( '#preview .navigation .open-panel .fa' ).on( 'click', function() {
  $( '#inner' ).addClass( 'open' );
  $( '#inner' ).removeClass( 'closed' );
});

$( '#inner .navigation .close-panel .fa' ).on( 'click', function() {
    $( '#inner' ).addClass( 'closed' );
});
