CSS Animation Preview
Preview CSS animations and copy the code for common effects.
Seeing animations before you use them
A CSS animation is hard to judge from code alone — you need to see it move to know if it feels right. This previews common animations, from fades and slides to bounces and spins, and copies the code, so you can pick and tune an effect by watching it rather than imagining it.

Animation that serves, not distracts
Good interface animation is mostly invisible: it guides attention, smooths transitions, and gives feedback that something happened, making an interface feel responsive and alive. The failure mode is animation for its own sake — effects that are too long, too bouncy, or everywhere, which quickly become annoying and slow the experience down. The best animations are quick and subtle, easing motion rather than showing off. It is also worth respecting users who prefer reduced motion, since animation can cause discomfort for some. Previewing an effect lets you judge whether it enhances the interface or just draws attention to itself, which is the line between polish and irritation.

Should I consider users who dislike motion?
Yes — some people prefer reduced motion, and animation can cause discomfort, so it is good practice to respect that preference.
