Last Updated : 15 Feb, 2021

The color-changing effect of a button is very common but what we are going to do a slightly advanced version of this effect. The background will change like a clip effect rotating at some particular angle. Approach: The approach is to provide two or three background and then rotating them on different angles. HTML Code: In this section, we will use HTML code to design the body structure.

html

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content=
        "width=device-width, initial-scale=1.0" />
    <title>Button effect</title>
</head>

<body>
    <a href="#">GeeksforGeeks</a>
</body>

</html>

CSS Code: In this section, we will follow some steps to design the button effect.

Step 1: First, we set the position of button and then use text-decoration property to remove underline from link. Also, set the width, height, color and background color of a button.
Step 2: Here we apply the second background with rotation using the before selector. We have used z-index to display this background at the top of other one.
Step 3: Now, apply final background with a different degree of rotation using nested selection of both hover and before selector.

Tip: You can change the degree of rotation to change the effect a bit according to your need. Below is the implementation of the above three steps.

CSS

<style>
    body {
        padding: 0;
        margin: 0;
    }

    a {
        position: absolute;
        top: 40%;
        left: 40%;
        transform: translate(-50%, -50%);
        width: 180px;
        height: 60px;
        color: white;
        text-decoration: none;
        text-align: center;
        padding-top: 30px;
        font-size: 20px;
        overflow: hidden;
        background: green;
    }

    a::before {
        content: "";
        position: absolute;
        width: 0;
        height: 0;
        left: 0;
        bottom: 0;
        border-style: solid;
        border-color: #f00;
        border-width: 80px 100px;
        z-index: -1;
        transform: rotate(360deg);
        transition: 1s;
        transform-origin: left;
    }

    a:hover::before {
        border-color: #00f;
        transform: rotate(60deg);
    }
</style>
