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.
