AI Gradient Orb Loader
A soft orb of blurred color blobs drifting around each other while the whole sphere breathes, like a voice assistant listening. Two blobs are hue-rotated from your accent.
Also known as: siri orb animation, ai voice orb, gradient blob loader.

}Customizing this loader
- Color: set
--ldr-coloron the element or a parent. Currently previewing#3b82f6. - Size: set
--ldr-size. Every dimension in the snippet is derived from it. Currently previewing64px. - Speed: change the duration on the
animationshorthand. Delays on the children are relative, so they keep their rhythm. - Accessibility: the root carries
role="status"and anaria-labelso screen readers announce the wait. The reduced-motion rule at the end slows the animation for users who asked for less motion.
