    <h2>Animation</h2>
    <p>
      Ionic comes with a powerful Animation library based on the emerging Web Animation API. Trigger
      animations based on user actions, step (or "scrub") through during a drag gesture, or add
      realistic physics effects to your app. The Animation API is a major improvement over CSS animations.
