Can CSS3 Keyframes Animate Elements on Page Load Without JavaScript?

CSS3 Transition Animation on Page Load: A Possibility

Can CSS3 transitions seamlessly animate elements on page load without JavaScript's aid?

Exploring the Options:

The quest for a solution led to several avenues:

• CSS3 Transition-Delay: While effective in delaying hover effects, it's not applicable for page load.
• CSS3 Keyframes: Capable of animating on load, but their sluggish nature hindered usability.
• CSS3 Transition: Rapid execution, but no animation on page load.

The Revelation: Keyframes to the Rescue

Contrary to earlier beliefs, CSS3 Keyframes can indeed animate on page load.

Example: Sliding Menu

Observe a sleek navigation menu that glides into view using only CSS3:

@keyframes slideInFromLeft {
  0% {
    transform: translateX(-100%);
  }
  100% {
    transform: translateX(0);
  }
}

header {
  animation: 1s ease-out 0s 1 slideInFromLeft;
  background: #333;
  padding: 30px;
}

<header>
  <a href="#">Home</a>
  <a href="#">About</a>
  <a href="#">Products</a>
  <a href="#">Contact</a>
</header>
