Fun Facts

• CSS gradients were first implemented by WebKit in 2008 using a proprietary syntax — the standardized linear-gradient() syntax wasn't finalized until 2012 after three different syntax iterations.
• Animating the background-position of an oversized gradient is more performant than animating background-color, because position changes can be GPU-composited while color changes cannot.
• Stripe's famous animated gradient header, introduced around 2016, inspired thousands of imitators — it uses a large gradient background animated with CSS keyframes at 400% background-size.

FAQ

How is a gradient animated?

By animating the background-size and background-position. The gradient itself doesn't change; its window through the container shifts.

Is performance an issue?

Gradient animations can be expensive. Use `will-change: background-position` if jank appears. Transforms are cheaper than background animations for simple motion.

Can I have multiple colors transitioning?

Yes — a multi-stop gradient that slowly cycles. The tool shows popular presets (aurora, sunset, ocean) and custom multi-stop modes.

Will it drain battery?

Subtle animations are fine. Intense ones (fast movement, large elements) can impact battery on mobile. Test on device.
