How to make a pulse effect

In this article, I'll teach you how to make a pulse effect on an image.

HTML Code

  • First, we add our image inside <img> tag.
<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <meta http-equiv="X-UA-Compatible" content="IE=edge">    <meta name="viewport" content="width=device-width, initial-scale=1.0">    <title>Pulse Effect</title></head><body>    <img class="moonPulse" src="https://i.pinimg.com/564x/a1/01/e2/a101e22fc458c1110d418ee309f240c8.jpg"alt="moon pic"/></body></html>

CSS Code

  • Styling the body
  body{    display: flex;    align-items: center;    justify-content: center;    margin-top: 5em;    background: #000;}
  • Styling the image
.moonPulse{    animation: pulse 1s infinite;    border-radius: 50%;    width: 20em;}

Finally, adding pulse effect animation

 @keyframes pulse{      from{        box-shadow: 0 0 0 0 rgba(198, 182, 179, 0.85);      }      to{        box-shadow: 0 0 0 30px rgba(201, 48, 48, 0);      }  }
