Slide Transitions

Smooth animations

CSS transforms provide smooth, GPU-accelerated transitions.

Transform approach:

.carousel-track {
  display: flex;
  transition: transform 300ms ease-out;
  transform: translateX(calc(-100% * var(--current-index)));
}

Benefits:

GPU acceleration (transform is composited)
No layout recalculation
Smooth $60$ fps animation

Avoid: Animating left/right properties. They trigger layout.

Transition timing: $200$ - $400$ ms feels responsive. Ease-out provides natural deceleration.
