Learn How the CSS @keyframes and animation Properties Work

Summary

• The animation properties and the @keyframes rule are used to animate an element.
• The animation properties control how the animation should behave and the @keyframes rule controls what happens during that animation.
  • animation-name sets the name of the animation.
  • animation-duration sets the length of time for the animation.
• frames range from 0% to 100%.
