CSS Rainbow Effect Animation

This CSS code snippet helps you to create a rainbow effect animation. It uses CSS3 keyframes for the rotation of vibrant colors in a circular pattern. You can integrate this code into your project to create a rainbow-like loading spinner or background animation.

How to Create Rainbow Effect Animation Using HTML & CSS

1. First, integrate the HTML structure into your project. The code includes a container div with nested elements representing rotating circles. Customize the structure based on where you want to incorporate the rainbow effect.

<div class="team">
            <div class="cap">
                <div class="c0 c1"></div>
                <div class="c0 c2"></div>
                <div class="c0 c3"></div>
                <div class="c0 c4"></div>
                <div class="c0 c5"></div>
                <div class="c0 c6"></div>
                <div class="c0 c7"></div>
                <div class="c0 c8"></div>
                <div class="c0 c9"></div>
                <div class="c0 c10"></div>
                <div class="c0 c11"></div>
                <div class="c0 c12"></div>
                <div class="c0 c13"></div>
                <div class="c0 c14"></div>
                <div class="c0 c15"></div>
                <div class="c0 c16"></div>
                <div class="c0 c17"></div>
                <div class="c0 c18"></div>
                <div class="c0 c19"></div>
                <div class="c0 c20"></div>
                <div class="c0 c10"></div>
                <div class="c0 c21"></div>
                <div class="c0 c22"></div>
                <div class="c0 c23"></div>
                <div class="c0 c24"></div>
                <div class="c0 c25"></div>
                <div class="c0 c26"></div>
                <div class="c0 c27"></div>
                <div class="c0 c28"></div>
                <div class="c0 c29"></div>
                <div class="c0 c30"></div>
                <div class="c0 c31"></div>
                <div class="c0 c32"></div>
                <div class="c0 c33"></div>
                <div class="c0 c34"></div>
                <div class="c0 c35"></div>
                <div class="cvr"></div>
            </div>
        </div>

2. Now, Add the following CSS code to your stylesheet (between <style> tag or external CSS file). This code defines the appearance, size, and animation properties of each circle. Adjust the colors and sizes as needed to suit your project.

Feel free to customize the number and size of the circles. Adjust the colors to your preference by modifying the border colors in each circle class. Experiment with the animation duration and speeds if desired.
