CSS animation in email

Introduction

This example demonstrates how to perform several CSS transition animations in AMP for email.

Setup an Object to Animate

Set up some CSS for a square with rounded corners. This is the object we will be animating.

  .object{
    display: inline-block;
    border-radius: 20%;
    height: 100px;
    width: 100px;
    margin: 10px;
  }

Skew Animation

Hover on the square to see the object animate into a skewed position.

<div class="object skew"></div>

The following CSS defines an animation which skews the object -20 degrees (x,y). The transformation duration is set to 0.4 seconds and the animation effect is set to ease-in-out.

.skew {
  background-color: #f53b57;
  transition: transform .4s ease-in-out;
  transform: skew(0deg, 0deg);
}

.skew:hover{
  transition: transform .4s ease-in-out;
  transform: skew(-20deg, -20deg);
}

Rotation Animation

Hover on the square to see the object rotate.

<span>
  <div class="object rotate"></div>
  <div class="object rotate origin"></div>
  <div class="object rotate three-dimension"></div>
</span>

The following CSS defines a hover animation which rotates the object around differnt origin points, including a three dimensional rotation.

.rotate {
  background-color: #3c40c6;
  transition: transform .6s ease-in-out;
}

.rotate:hover{
  transition: transform .9s ease-in-out;
  transform: rotate(280deg);
}

.rotate.origin {
  background-color: #3c40c6;
  transition: transform .6s ease-in-out;
  transform: rotate(0deg);
  transform-origin: top left;
}

.rotate.origin:hover{
  transition: transform .9s ease-in-out;
  transform: rotate(-280deg);
  transform-origin: top left;
}

.rotate.three-dimension:hover{
  transition: transform .9s ease-in-out;
  transform: rotate3d(1, 2, -1, 280deg)
}

Translation Animation

Hover on the squares to see the objects animate to new positions.

<span>
  <div class="object movexy one"></div>
  <div class="object movexy two"></div>
  <div class="object movexy three"></div>
</span>

The following CSS defines a translation animation which moves the object to a new position (x,y).

.movexy {
  background-color: #05c46b;
  transition: transform .4s ease-in-out;
  transform: translate(0px, 0px);
}

.movexy.one:hover{
  transition: transform .4s ease-in-out;
  transform: translate(0px, -50px);
}

.movexy.two:hover{
  transition: transform .4s ease-in-out;
  transform: translate(0px, 50px);
}

.movexy.three:hover{
  transition: transform .4s ease-in-out;
  transform: translate(400px, -150px);
}

Rolling an object

Hover on the square to see the object roll across the view..

<span>
  <div class="object roll"></div>
</span>

The following CSS defines combines a transformation (rotation) with a translation animation to create a rolling effect.

.roll {
  background-color: #00d8d6;
  transition: transform 1.2s ease-in-out;
}

.roll:hover{
  transition: transform 1.4s ease;
  transform: translate(530px, 0px) rotate(360deg);
  transition-timing-function: cubic-bezier(.55,.07,.42,.54);
}

Scale Animation

Hover on the square to see the object animate into a new, larger size.

<div class="object scale"></div>

The following CSS defines an animation which scales the object's size.

.scale {
  background-color: #ffb8b8;
  transition: transform .4s ease-in-out;
}

.scale:hover{
  transition: transform .4s ease-in-out;
  transform: scale(2);
}

Down the drain

Hover on the squares to see the objects animate to new positions.

<span>
    <div class="object drain"></div>
</span>

The following CSS combines a few different transformations and translations to create the effect of an object going down a drain.

.drain {
  background-color: #ffd32a;
  transition: transform 1.4s ease-in-out;
}

.drain:hover{
  transition: transform 1.4s ease-in-out;
  transform: scale(0) skew(-20deg) rotate(-90deg) translate(430px, 220px);
  transition-delay: .2s;
}
