Rotate a circle with CSS

Ever wonder how people animate images or anything? Like this image below?? Well today is your lucky day, It turns out to be simple to make.

Disclaimer: Having basic CSS Animation knowledge would really help.

Start with the basic HTML template. You can use any image

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>CSS Rotating Circle</title>
    <link rel="stylesheet" type="text/css" href="circle.css">
</head>
<body>
    <h1>CSS Rotating Circle</h1>

    <main>
        <div>
            <img src="iconmonstr-circle-5.svg" alt="circle">
        </div>
    </main>
</body>
</html>
Enter fullscreen mode Exit fullscreen mode

This boring Image should show up on the browser.

Let's spice it up a little, shall we?

/* circle.css */
*{
    margin: 0px;
    padding: 0px;
    box-sizing: border-box;
}
body{
    width: 90%;
    margin: auto;
    text-align: center;
    padding: 20px 0px;
    font-family: Arial;
}
main{
    height: 500px;
    display: grid;
    align-items: center;
}
Enter fullscreen mode Exit fullscreen mode

you can use other trick to center the contents, I went with Grid display: grid; and align-items: center;.

Increase the image size a little with the style below, since we are using an SVG image.

main img{
    width: 200px;
    height: 200px;
    animation-name: rotate;
    animation-duration: 5s;
    animation-iteration-count: infinite;
    animation-timing-function: linear;
    border-radius: 50%;
}
Enter fullscreen mode Exit fullscreen mode

border-radius can be optional. Everything should look cute now like the image below.

We can't animate anything if we don't have the @keyframes specified.

@keyframes rotate{
    from{ transform: rotate(-360deg); }
    to{ transform: rotate(360deg); }
}
Enter fullscreen mode Exit fullscreen mode

And voilà, its done. Also note that animation-name: and @keyframes share the same name rotate.

You can play with it or even add more functionality to it, like starting and stopping the animation with JavaScript.

Thanks for reading.
