Scroll Reveal Animations

Scroll down to watch elements reveal themselves with different directions, timings, and easing curves. Over 20 animated elements on this page.

Fade Up

The most common reveal direction. Elements slide up and fade in as they enter the viewport.

Welcome to RevFlow OS

This text block fades up smoothly from below. Every element on this page uses the IntersectionObserver API to detect when it enters the viewport, then applies a CSS transition.

Zero Dependencies

No animation library required. Pure CSS transforms and transitions, triggered by a tiny JavaScript observer. This means zero impact on bundle size.

Slide from Left

Another Left Entry

Multiple items can slide from the left in sequence when stagger delays are applied.

Fade Right

Slide from Right

Perfect for alternating layouts where left and right elements enter from opposite sides.

Combine left and right reveals for a dynamic reading experience.

Fade Scale

Elements scale up from a smaller size while fading in.

Pop In Effect

The scale reveal creates an eye-catching "pop" effect, great for hero elements and key statistics.

Fade Down

Elements drop down from above.

Dropping Down

The fade-down direction works well for navigation items, dropdown menus, and top-of-section headers.

Gravity Effect

Combined with a slight bounce easing, this can create a natural "falling into place" effect.

Staggered Cards

Cards appear one after another with increasing delays.
