CSS3 Transition - Fade out effect
CssCss TransitionsCss Problem Overview
I am trying to implement the "fade out" effect in pure CSS. Here is the fiddle. I did look into a couple of solutions online, however, after reading the documentation online, I am trying to figure out why the slide animation would not work. Any pointers?
.dummy-wrap {
animation: slideup 2s;
-moz-animation: slideup 2s;
-webkit-animation: slideup 2s;
-o-animation: slideup 2s;
}
.success-wrap {
width: 75px;
min-height: 20px;
clear: both;
margin-top: 10px;
}
.successfully-saved {
color: #FFFFFF;
font-size: 20px;
padding: 15px 40px;
margin-bottom: 20px;
text-align: center;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
background-color: #00b953;
}
@keyframes slideup {
0% {top: 0px;}
75% {top: 0px;}
100% {top: -20px;}
}
@-moz-keyframes slideup {
0% {top: 0px;}
75% {top: 0px;}
100% {top: -20px;}
}
@-webkit-keyframes slideup {
0% {top: 0px;}
75% {top: 0px;}
100% {top: -20px;}
}
@-o-keyframes slideup {
0% {top: 0px;}
75% {top: 0px;}
100% {top: -20px;}
}
<div class="dummy-wrap">
<div class="success-wrap successfully-saved">Saved</div>
</div>

Here is another way to do the same.
fadeIn effect
.visible {
visibility: visible;
opacity: 1;
transition: opacity 2s linear;
}
fadeOut effect
.hidden {
visibility: hidden;
opacity: 0;
transition: visibility 0s 2s, opacity 2s linear;
}
UPDATE 1:
I found more up-to-date tutorial CSS3 Transition: fadeIn and fadeOut like effects to hide show elements and Tooltip Example: Show Hide Hint or Help Text using CSS3 Transition here with sample code.
UPDATE 2: (Added details requested by @big-money)
When showing the element (by switching to the visible class), we want the visibility:visible to kick in instantly, so it’s ok to transition only the opacity property. And when hiding the element (by switching to the hidden class), we want to delay the visibility:hidden declaration, so that we can see the fade-out transition first. We’re doing this by declaring a transition on the visibility property, with a 0s duration and a delay. You can see a detailed article here.
I know I am too late to answer but posting this answer to save others time. Hope it helps you!!

You can use transitions instead:
.successfully-saved.hide-opacity{
opacity: 0;
}
.successfully-saved {
color: #FFFFFF;
text-align: center;
-webkit-transition: opacity 3s ease-in-out;
-moz-transition: opacity 3s ease-in-out;
-ms-transition: opacity 3s ease-in-out;
-o-transition: opacity 3s ease-in-out;
opacity: 1;
}

Since display is not one of the animatable CSS properties.
One display:none fadeOut animation replacement with pure CSS3 animations, just set width:0 and height:0 at last frame, and use animation-fill-mode: forwards to keep width:0 and height:0 properties.
@-webkit-keyframes fadeOut {
0% { opacity: 1;}
99% { opacity: 0.01;width: 100%; height: 100%;}
100% { opacity: 0;width: 0; height: 0;}
}
@keyframes fadeOut {
0% { opacity: 1;}
99% { opacity: 0.01;width: 100%; height: 100%;}
100% { opacity: 0;width: 0; height: 0;}
}
.display-none.on{
display: block;
-webkit-animation: fadeOut 1s;
animation: fadeOut 1s;
animation-fill-mode: forwards;
}

<html>
<head>
<style>
.animated {
background-color: green;
background-position: left top;
padding-top:95px;
margin-bottom:60px;
-webkit-animation-duration: 10s;animation-duration: 10s;
-webkit-animation-fill-mode: both;animation-fill-mode: both;
}
@-webkit-keyframes fadeOut {
0% {opacity: 1;}
100% {opacity: 0;}
}
@keyframes fadeOut {
0% {opacity: 1;}
100% {opacity: 0;}
}
.fadeOut {
-webkit-animation-name: fadeOut;
animation-name: fadeOut;
}
</style>
</head>
<body>
<div id="animated-example" class="animated fadeOut"></div>

You forgot to add a position property to the .dummy-wrap class, and the top/left/bottom/right values don't apply to statically positioned elements (the default)
Solution 6 - Css
.fadeOut{
background-color: rgba(255, 0, 0, 0.83);
border-radius: 8px;
box-shadow: silver 3px 3px 5px 0px;
border: 2px dashed yellow;
padding: 3px;
}
.fadeOut.end{
transition: all 1s ease-in-out;
background-color: rgba(255, 0, 0, 0.0);
box-shadow: none;
border: 0px dashed yellow;
border-radius: 0px;
}
Solution 7 - Css
Use the forwards fill-mode in CSS for it to remain on the last part of the animation.
I suggest using transform: tranlsateY(-20px); instead of using css positions, but if you insist of using it then set the .dummy-wrap position into absolute
.dummy-wrap {
animation: slideup 2s forwards;
-moz-animation: slideup 2s forwards;
-webkit-animation: slideup 2s forwards;
-o-animation: slideup 2s forwards;
position: absolute;
}
@keyframes slideup {
0% {
top: 0px;
}
75% {
top: 0px;
}
100% {
top: -20px;
}
}
<div class="dummy-wrap">
<div class="success-wrap successfully-saved">Saved</div>
</div>
