Simple Material design CSS animation

Do you have heard of material design? It’s the most popular design language in the world. In this tutorial, we will learn how to make a simple CSS animation following material design animation guidelines. So, let’s get started!

Preparing the HTML

First, we have to prepare the HTML. Create an HTML file and put/or type the code below in that file.

<div id="main">
  <div id="element">+</div>
</div>

Ok, now that we prepared our HTML we’ll style the components.

Styling the HTML components

Here, we will style the components that we made.

Adding some padding and a background to the body

body {
  background: #ECEFF1;
  padding: 20px;
}

Styling the container

We’ll style the resizing container.

#main {
   position: relative;
   overflow: hidden;
   border-radius: 4px;
   height: 200px;
   width: 600px;
   background: rgba(255, 255, 255, 1);
   box-shadow: 0 3px 1px -2px rgba(0,0,0,.2),0 2px 2px 0 rgba(0,0,0,.14),0 1px 5px 0 rgba(0,0,0,.12);
}

Styling the button

Now that we have a container, we’ll style the button (FAB).

#element {
  position: absolute;
  bottom: 40px;
  right: 40px;
  display: flex;
  width: 50px;
  height: 50px;
  align-items: center;
  justify-content: center;
  font-size: 2rem;
  font-family: sans-serif;
  color: #fff;
  background: #c51162;
  border-radius: 50px;
  box-shadow: 0 7px 8px -4px rgba(0, 0, 0, 0.2), 0 12px 17px 2px rgba(0, 0, 0, 0.14), 0 5px 22px 4px rgba(0, 0, 0, 0.12);
}

#element:after {
  content: "";
  border-radius: 50px;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%) scale(0);
  height: 100%;
  width: 100%;
  background: rgba(255, 255, 255, 1);
  z-index: 9;
}

This is what we get.

Animating !

Here’s the last step we’ll start animating!

Animating the container

We’ll add the resizing animation to the container.

#main {
  animation: mainanimation 4s ease infinite;
}

@keyframes mainanimation {
  0% {
    width: 300px;
    height: 400px;
  }
  25% {
    width: 400px;
    height: 200px;
  }
  50% {
    width: 700px;
    height: 600px;
  }
  75% {
    width: 400px;
    height: 600px;
    box-shadow: 0 11px 15px -7px rgba(0, 0, 0, 0.2), 0 24px 38px 3px rgba(0, 0, 0, 0.14), 0 9px 46px 8px rgba(0, 0, 0, 0.12);
  }
  100% {
    width: 300px;
    height: 400px;
  }
}

Animating the button

We’ll add the ripple effect and clicking animation to the button.

#element {
  animation: fabanimation 1s ease infinite;
}

#element:after {
  animation: fabripple 1s infinite ease;
}
@keyframes fabripple {
  0% {
    transform: translate(-50%, -50%) scale(0);
  }
  20% {
    transform: translate(-50%, -50%) scale(0.7);
    opacity: 0.8;
  }
  100% {
    transform: translate(-50%, -50%) scale(1);
    background: rgba(255, 255, 255, 0);
  }
}

@keyframes fabanimation {
  0%,
  100% {
    box-shadow: 0 0px 0px -4px rgba(0, 0, 0, 0.2), 0 12px 17px 2px rgba(0, 0, 0, 0.14), 0 5px 22px 4px rgba(0, 0, 0, 0.12);
  }
  50% {
    box-shadow: 0 11px 15px -7px rgba(0, 0, 0, 0.2), 0 24px 38px 3px rgba(0, 0, 0, 0.14), 0 9px 46px 8px rgba(0, 0, 0, 0.12);
    transform: scale(0.9);
  }
}

YAY! we’ve created our animation. Here’s what we get.
