CSS Heart Shape & Heartbeat Animation

Last year I posted the tutorial Fast & easy CSS Valentine’s Day Animation (Heartbeat), were to create the heartbeat I used the .png file. Today I will show you how to create the heart shape and heartbeat animation using just pure CSS.

What do you need to do?

1. Add HTML
2. Add CSS
3. Add CSS Animation

Step1.

Add HTML

<div class="container">
      <div class="heart"></div>
  </div>

Step2.

Add CSS

Set the colour and the position of the background and the elements:

body {
  background-color: #fae1dd;
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}
  
.container {
  position: relative;
  animation: .8s beat infinite;
}

Create the heart:

.heart {
  position: relative;
  background-color: red;
  display: inline-block;
  height: 60px;
  top:0;
  left:0;
  transform: rotate(-45deg);
  width:60px;
}
  
.heart:before, .heart:after {
  content:"";
  background-color: red;
  border-radius:50%;
  height: 60px;
  width: 60px;
  position: absolute;
  width: 60px;
  }
  
.heart:before {
  top:-30px;
  left:0;}
  
.heart:after {
  left:30px;
  top:0;}

Step3.

Add CSS Animation

@keyframes beat {
  0% {
    transform: scale(1);
  }
  25% {
    transform: scale(1.1);
  }
  40% {
    transform: scale(1);
  }
  60% {
    transform: scale(1.1);
  }
  100% {
    transform: scale(1);
  }
}
