Keyframes

ELI5 — The Vibe Check

Keyframes are like the storyboard for a CSS animation. You tell the browser 'at the start, be here; at the middle, be there; at the end, be somewhere else' and the browser fills in all the frames in between. You're basically a movie director now.

Real Talk

@keyframes defines named animation sequences with percentage-based or from/to waypoints. Each keyframe specifies CSS property values at that point in the animation timeline. The browser interpolates between keyframes to create smooth transitions.

@keyframes fadeSlideIn {
  0% { opacity: 0; transform: translateY(20px); }
  100% { opacity: 1; transform: translateY(0); }
}
