How to use an animated gradient background
Animated gradients work well for hero sections, loading states, and accent backgrounds where subtle, ambient motion adds energy without pulling focus from content.
- Pick 2 to 3 colors and an angle that fits your brand.
- Choose shift for a slow ambient background, pulse for a subtle loading or accent state.
- Keep duration slow (6 to 12 seconds) so the motion feels calm.
- Copy the CSS into your background element's stylesheet.
Avoid placing small body text directly over a fast-moving gradient. Respect prefers-reduced-motion for users sensitive to persistent motion.
A background larger than the element shifts position, rotation, or opacity through a CSS keyframe animation.
Animating background-position is lightweight, but very large full-screen gradients should still be tested on lower-end devices.
FAQ
Gradient Animation Generator FAQ
How do animated CSS gradients work?
The background is rendered larger than the element (background-size over 100%) and a CSS keyframe animation shifts its position, rotation, or opacity over time.
Will an animated gradient hurt performance?
Animating background-position is lightweight compared to animating layout properties, but very large full-screen gradients on low-end devices can still cost some paint time. Test on the target device.
Is this gradient animation generator free?
Yes. Adjust the controls and copy the CSS for free, with no account required.
