Add Twitch-like hover effect to a picture

#css #styling #hover #html

I based this code on the CodePen link by Arnaud Delante, but I thought it might be handy to make an article of this.

It's pretty straight forward and you can change stuff to your liking.

1. HTML

Import a stylesheet, show some pictures and write out the HTML code.

For every picture that needs the hover effect, we have to wrap it in a separate container div, like this:

<!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">
    <link rel="stylesheet" type="text/css" href="style.css">
    <title>Document</title>
</head>
<body>
    <div class="container">
        <img class="picture" src="picture.jpeg" alt="picture">
    </div>
    <div class="container">
        <img class="picture" src="picture2.jpeg" alt="picture">
    </div>
</body>
</html>

2. CSS

Use your class names and use this CSS code:

body {
    text-align: center;
}

.container {
    display: inline-block;
    margin: 50px;
    background-color: red;
  }

.container:before,
.container:after {
    display: block;
    background-color: red;
    width: 8px;
    height: 8px;
    position: absolute;
    transition: all .15s ease;
}

.container:before {
    top: 0;
    left: 0;
    transform-origin: top left;
    transform: rotate(-45deg) scale(0);
}

.container:after {
    right: 0;
    bottom: 0;
    transform-origin: bottom right;
    transform: rotate(45deg) scale(0);
}

.picture {
    height: 300px;
    display: block;
    transform: translate(0, 0);
    transition: all .15s ease;
    z-index: 10;
}

.container:hover .picture {
    transform: translate(6px, -6px);
}

.container:hover:before {
    transform: rotate(-45deg) scale(1);
}

.container:hover:after {
    transform: rotate(45deg) scale(1);
}
