This project demonstrates how to create an engaging loading animation using pure CSS.
The animation features a rotating background color and a loader composed of** 20 spinning dots **that pulsate sequentially. The background hue shifts continuously, creating a dynamic visual effect. Each dot is positioned using CSS variables and animated with keyframes to scale up and down in a rhythmic pattern.
Key Features:
- Rotating Background: Smooth color transitions using hue-rotate.
- Pulsating Dots: Sequential animation delays for a wave effect.
- Pure CSS: No JavaScript required, ensuring lightweight performance.
Usage
- Embed the HTML in your webpage.
- Add the CSS to your stylesheet.
- Adjust the number of spans and their styles as needed for different visual effects. This loader is perfect for adding a modern, visually appealing touch to your web projects.

Pretty, but how is it 'interactive'?
Thank you for your comment! You're right; the current implementation isn't interactive. The animation is purely visual at the moment. However, I appreciate your feedback and will be adding interactive features, like a bounce effect on touch, in the coming days.
@jonrandy Check this out Now!! Now its interactive
Interactive means it does something when the user touches or swipes it. It's currently not interactive but I would like if it does a little bounce when a user touches it
@mosesb Check this out Now!! Now its Interactive
Great work
Smooth ...Nice one!
