1. Animating Properties: CSS allows you to animate various properties such as width, height, color, opacity, transform, background, and more.

  2. @keyframes: Define keyframes using @keyframes, specifying intermediate states of element properties from start to finish.

    @keyframes slide-in {
      from {
        transform: translateX(-100%);
      }
      to {
        transform: translateX(0);
      }
    }
    
  3. animation Property: Use the animation property to apply animations to an element, including parameters like animation name, duration, delay, easing function, and iteration count.

    .box {
      animation: slide-in 1s ease-out 0.5s forwards;
    }
    
  4. Types of Animations: CSS allows you to create various types of animations, including movement, resizing, color change, rotation, opacity change, and more.

  5. Pseudo-classes: Utilize pseudo-classes like :hover or :focus to trigger animations when users interact with elements.

    .button {
      transition: background-color 0.3s ease;
    }
    .button:hover {
      background-color: #ff0000;
    }
    
  6. Performance: CSS animations can be more performant than JavaScript-based animations, especially on mobile devices.

  7. Combining Animations: Combine multiple animations by applying multiple @keyframes or using sequential or parallel animations.

    .box {
      animation: slide-in 1s ease-out 0.5s forwards, fade-in 0.5s ease-out 1.5s forwards;
    }
