Pulse!

The code!

First we will create the HTML code and link to the stylesheet in our case "test.css"

<!doctype html> <html> <head> <meta charset="utf-8"/> <title>Test</title> <link rel="stylesheet" href="test.css" /> </head> <body> </body> </html>then we create the CSS code body { background-color: #bae8fa; animation: ani 120s linear infinite; } @keyframes ani { 0% { background-color: #bae8fa; } 20% { background-color: #25e063; } 40% { background-color: #e0aa4d; } 60% { background-color: #ec6e6e; } 80% { background-color: #5dabd6; } 100% { background-color: #bae8fa; } } and that is that now you have your Pulse!
