CSS3 Transition - Fade out effect

People also ask

How do I fadeIn and fadeOut in CSS?

The jQuery fadeToggle() method toggles between the fadeIn() and fadeOut() methods. If the elements are faded out, fadeToggle() will fade them in.

What is a fadeOut transition?

In the post-production process of film editing and video editing, a dissolve (sometimes called a lap dissolve) is a type of film transition in which one sequence fades over another. The terms fade-out (also called fade to black) and fade-in are used to describe a transition to and from a blank image.

How do you add transition effects in css3?

To make the transition occur, you must specify at least two things — the name of the CSS property to which you want to apply the transition effect using the transition-property CSS property, and the duration of the transition effect (greater than 0) using the transition-duration CSS property.


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;
}

This is the working code for your question.
Enjoy Coding....

<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>

   </body>
</html>

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)
