Welcome to our growing collection of animation patterns. These patterns try to demonstrate how you can create engaging animations and interactions while still respecting user's preferences for motion. They also support all modern browsers, so you can use them with confidence. This pattern shows how to create infinitely animated letter effects that respect user's motion preferences. This pattern shows how to create infinitely animated word effects that respect user's motion preferences. This pattern shows how to create interactive letter effects that respect user's motion preferences. This pattern shows how to create interactive word effects that respect user's motion preferences.
