Infinite scroll

Loads additional content automatically as users scroll down.

What it solves

Infinite Scroll is a UI pattern that dynamically loads more content as users scroll down a page, eliminating the need for pagination or manual interaction. It provides a seamless browsing experience by continuously appending new items to the current view. This pattern is commonly used in social media feeds, search results, and content-heavy websites to keep users engaged without interruptions.

When to use

Use Infinite Scroll when you need to dynamically load more content as users scroll without requiring manual pagination. Common scenarios include:

• Social media feeds – e.g., Twitter, Instagram, Facebook, where users consume an endless stream of content.
• News and blog sites – e.g., showing a continuous stream of articles.
• E-commerce product listings – e.g., dynamically loading more items as users explore the catalog.
• Search results – e.g., reducing friction in discovering relevant items.
• Media galleries – e.g., loading more images/videos as users scroll.

When to avoid

• When users need to find specific content quickly – Paginated results may be more efficient.
• For structured navigation – If users need to compare items or revisit previous results, pagination provides better control.
• If performance is a concern – Infinite scroll can lead to high memory usage and slow rendering.
• For content requiring user actions – If users frequently need to interact with elements (e.g., filling forms), infinite scrolling can be disruptive.
• When reaching the footer is important – Users may struggle to access footer content if new items keep loading.

Implementation workflow

1. Confirm the pattern matches the problem and constraints before copying the example.
2. Start from the anatomy and examples in references/pattern.md, then choose the smallest viable variation.
3. Apply accessibility, performance, and interaction guardrails before layering visual polish.
4. Use the testing guidance to verify behavior across keyboard, screen reader, responsive, and failure scenarios.

Accessibility guardrails

Do's ✅

• Ensure content is focusable – New items should be reachable via keyboard navigation.
• Announce new content dynamically using ARIA live regions (aria-live="polite").
• Provide an alternative to infinite scrolling – Offer pagination or a "Load More" option.
• Ensure users can pause or stop loading – Unexpected content updates can be disorienting. Don'ts ❌
• Avoid relying solely on scrolling – Users with assistive technologies may need alternative navigation.
• Don't change content order unexpectedly – Screen readers should process content sequentially.
