Aurora CSS Effect Tutorial - How to Create Aurora

Learn how to create the aurora CSS effect. Animated gradient blobs, layered radial gradients, organic color movement.

AI agents write a linear-gradient with two colors and call it done. A real aurora needs 3+ color blobs as separate elements, each with filter: blur(60px), animated on different non-divisible durations (19s, 25s, 15s) so the pattern never repeats. Adding hue-rotate makes colors shift continuously. Agents never create separate blobs, never blur them, and use a single animation timing for everything.

Copy and paste this aurora CSS code into your AI coding agent (Claude, ChatGPT, Cursor) for instant implementation.

Aurora

AI agents write a linear-gradient with two colors and call it done. A real aurora needs 3+ color blobs as separate elements, each with filter: blur(60px), animated on different non-divisible durations (19s, 25s, 15s) so the pattern never repeats. Adding hue-rotate makes colors shift continuously. Agents never create separate blobs, never blur them, and use a single animation timing for everything.

Examples

Living Color
Four blurred blobs drift independently at 19s, 25s, 15s, and 21s. The non-divisible durations mean the pattern never exactly repeats.
Hue Rotation
Each blob cycles through hue-rotate(360deg) at a different speed, so the color palette continuously shifts without hardcoded values.
