SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Creating a smooth, gap-free infinite scrolling marquee for logos, testimonials, or tags is tricky—naive implementations jump, stutter, or break the loop. This Skill provides a proven workflow for building seamless marquees that loop perfectly.

Core Features & Use Cases

  • Seamless Loop Technique: Duplicate the item sequence and animate the track with a linear transform from 0 to -50% so the end and beginning match perfectly.
  • Stability & Accessibility Guardrails: Keep item widths stable to prevent jumps, mask or fade edges at section boundaries, and respect prefers-reduced-motion with a static or slowed fallback.
  • Use Case: A landing page needs a continuously scrolling strip of client logos or feature chips in the header. Apply this Skill to build a responsive marquee that loops infinitely without visible seams and pauses on hover when useful.

Quick Start

Use the marquee-loop skill to add a seamless infinite scrolling logo strip to my landing page header.

Frequently Asked Questions about marquee-loop

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a seamless infinite marquee in CSS?▼

Duplicate the item sequence so the end matches the beginning, then animate the track with a linear transform from 0 to -50%. Because the content repeats exactly, the loop resets invisibly with no jump or gap.

Why does my marquee animation jump or stutter at the loop point?▼

Jumps happen when item widths change during animation or the duplicated sequence does not match the original exactly. Keep item widths stable and ensure the duplicated group is pixel-identical to the first.

How do I make a marquee accessible for reduced motion users?▼

Respect the prefers-reduced-motion media query by replacing the animation with a static wrapped layout or very slow movement. This prevents vestibular discomfort while keeping the content readable.

When should I avoid using a scrolling marquee?▼

Avoid marquees for unique content users must read carefully, since moving text is hard to follow. Also avoid heavy CPU-intensive shadows or filters on every moving item, which degrade rendering performance.

Can I pause a CSS marquee on hover?▼

Yes, pause or slow the marquee on hover using animation-play-state, but only when the interaction is useful, such as letting users read a testimonial. Do not add hover pauses that serve no purpose.
