12 Principles Of Animation

Animation can make a website feel alive and smooth. But bad animation can confuse users. This tool checks your animation code against Disney's 12 principles adapted for the web. It finds problems with timing, easing, physics, and staging. It outputs each issue with the exact file and line number so you can fix it fast. Developers and designers can use it to make motion feel natural and polished.

The rules are simple. User animations must finish in under 300 milliseconds. Entrances should ease out, exits should ease in. Interactive elements need a pressed state with a tiny scale change. Only one element should animate at a center of attention. The tool reads your CSS, JavaScript, or framework files and gives a clear report.

This skill helps you avoid common mistakes like linear easing for motion or too much stagger delay. It turns professional animation wisdom into automatic checks. You get better animation quality without memorizing all the rules.
