How to create CSS3 bounce effect

If all you need is a very simple bounce, it's as easy as just changing the transition function from ease-in to something else, such as a cubic-bezier.

An example of a cubic-bezier function that bounces would be

cubic-bezier(0.175, 0.885, 0.32, 1.275)

A full example:

div {
    background:  tomato;
    width: 100px;
    height: 100px;
    margin-bottom: 10px;
    transition: transform 0.3s cubic-bezier(0.175, 0.885, 0.32, 1.275);
    transform-origin: top left;
}
div:hover {
    -webkit-transform: scale3d(5, 5, 5);
    transform: scale3d(5);
}
<div></div>
<div></div>
<div></div>

You can find a few examples of other easings at easings.net, or a full cubic-bezier editor at cubic-bezier.com.


I'm a fan of animate.css

Coincidentally, the first animation is bounce.

You can extract the code you need from the css file.

Using the animate.css framework i've extracted their bounce animation and have created a snippet below:

@-webkit-keyframes bounce {
  0%, 20%, 53%, 80%, 100% {
    -webkit-transition-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
    transition-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
    -webkit-transform: translate3d(0,0,0);
    transform: translate3d(0,0,0);
  }

  40%, 43% {
    -webkit-transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    -webkit-transform: translate3d(0, -30px, 0);
    transform: translate3d(0, -30px, 0);
  }

  70% {
    -webkit-transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    -webkit-transform: translate3d(0, -15px, 0);
    transform: translate3d(0, -15px, 0);
  }

  90% {
    -webkit-transform: translate3d(0,-4px,0);
    transform: translate3d(0,-4px,0);
  }
}

@keyframes bounce {
  0%, 20%, 53%, 80%, 100% {
    -webkit-transition-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
    transition-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
    -webkit-transform: translate3d(0,0,0);
    transform: translate3d(0,0,0);
  }

  40%, 43% {
    -webkit-transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    -webkit-transform: translate3d(0, -30px, 0);
    transform: translate3d(0, -30px, 0);
  }

  70% {
    -webkit-transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    transition-timing-function: cubic-bezier(0.755, 0.050, 0.855, 0.060);
    -webkit-transform: translate3d(0, -15px, 0);
    transform: translate3d(0, -15px, 0);
  }

  90% {
    -webkit-transform: translate3d(0,-4px,0);
    transform: translate3d(0,-4px,0);
  }
}

.bounce {
  -webkit-animation-name: bounce;
  animation-name: bounce;
  -webkit-transform-origin: center bottom;
  transform-origin: center bottom;
}

.animated {
  -webkit-animation-duration: 1s;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
}

div{background:red; padding:50px;}
<div class="bounce animated">bounce</div>
