fade in out animation css code example

Example 1: css fade out

/* Just add .fade-out class to element */

.fade-out {
	animation: fadeOut 2s;
  	opacity: 0;
}

@keyframes fadeOut {
  from {
  	opacity: 1;
  }
  to {
 	opacity: 0;
  }
}

Example 2: css fade out

/* Answer to: "css fade out" */

/*
  With the code below, all you have to do is use JavaScript to
  give the element ".hide-opacity" and it'll fade-out.

  Feel free to edit this code so it works on hover, focus, active
  or any other special selector possible with CSS and of course
  feel free to use this code with your JavaScript too!
*/

.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;
}

.successfully-saved.hide-opacity {
    opacity: 0;
}

Example 3: in 10 seconds fade in a card html css

Your issue stems from applying two animations at once that you actually want to run in sequence. To get this working reliably you have two options:

CSS only: http://jsfiddle.net/marionebl/M9LR6/

Note opacity: 0; to keep the message hidden when the animation completes. Plus: This won't work in IE <= 9, it does not support keyframe animations: http://caniuse.com/#feat=css-animation

@keyframes fadeInOut {
    0% {
        opacity: 0;
    }
    16% {
       opacity: 1;
    }
    84% {
       opacity: 1;
    }
    100% {
       opacity: 0;
    }
}

.message {
    width: 400px;
    margin: 0 auto;
    opacity: 0;
    text-align: center;
   -webkit-animation: fadeInOut 6s;
   animation: fadeInOut 6s;
}

Is somewhat more flexible and easier to change, supports IE9.

CSS:

@-webkit-keyframes fadeIn {
    from {
        opacity: 0;
    }
    to {
        opacity: 1;
    }
}
@keyframes fadeIn {
    from {
        opacity: 0;
    }
    to {
        opacity: 1;
    }
}

@-webkit-keyframes fadeOut {
    from {
        opacity: 1;
    }
    to {
        opacity: 0;
    }
}
@keyframes fadeOut {
    from {
        opacity: 1;
    }
    to {
        opacity: 0;
    }
}

.fadeIn {
    -webkit-animation: fadeIn;
    animation: fadeIn;
    opacity: 1;
}

.fadeOut {
    -webkit-animation: fadeOut;
    animation: fadeOut;
    opacity: 0;
}

.fast {
    -webkit-animation-duration: 1s;
    animation-duration: 1s
}

.message {
    width: 400px;
    margin: 0 auto;
    text-align: center;
}
JS:

var $message = $('.message');
$message.addClass('fadeIn fast');

setTimeout(function(){
   $message.removeClass('fadeIn').addClass('fadeOut');
}, 5000);
