Masked Reveal
Reveal headlines word by word through an overflow mask on scroll.
What it is
A GSAP ScrollTrigger pattern that splits a heading into masked word spans and staggers them upward as the text enters the viewport. Includes a React cleanup pattern.
Create masked staggered word reveals on scroll with GSAP ScrollTrigger. Use when headings, hero copy, section titles, or editorial text should reveal word-by-word through an overflow mask as they enter the viewport.
Why it matters for design
- Word-level stagger reads calmer and more editorial than letter-level animation.
- Screen readers still get the full text through an aria-label.
- Reduced-motion users see static text with no transform applied.
What it covers
- Use when
- Motion defaults
- CSS mask
- GSAP ScrollTrigger
- React cleanup pattern
- Quick checks
