To prototype motion design solutions, you need to take advantage of advanced and interactive tools. Animation is a great way to create and edit your motion ideas, using keyframes, curves, timelines, and layers. You can use animation tools like After Effects, Lottie, or Principle to create your animation and export or share your animation files or previews. Coding is another way to implement and customize your motion ideas using languages, frameworks, and libraries. HTML, CSS, JavaScript, React, or Flutter are coding tools you can use to code your motion and test or debug your motion code or output. Testing is a great way to evaluate and validate your motion ideas using methods, metrics, and feedback. Google Analytics, Hotjar, or UserTesting are testing tools you can use to test your motion and measure or collect data or insights on your motion performance or user experience.
