Masonry

Pinterest-style vertical-pack grid using CSS columns for efficient masonry layout without JavaScript.

Components Masonry

<arc-masonry>

Overview

Masonry is a layout primitive that arranges variable-height children into a Pinterest-style vertical-pack grid using pure CSS columns. Items flow top-to-bottom within each column, filling vertical space efficiently without leaving gaps — the classic masonry pattern used in image galleries, card feeds, and content discovery interfaces. The component uses CSS `column-count` and `column-gap` under the hood, which means layout is handled entirely by the browser with zero JavaScript overhead. Each child element is automatically placed into the shortest column, creating a tightly packed grid that adapts to varying content heights. The `columns` prop controls the number of columns, while the `gap` prop maps to design system spacing tokens for consistent rhythm. Use Masonry when your content items have naturally varying heights — image galleries, blog post cards, testimonial collections, or any feed where uniform row heights would waste space. For uniform aspect-ratio grids, use AspectGrid instead. For responsive column-to-stack behavior, combine Masonry with ResponsiveSwitcher.

Guidelines

When to use

  • Use for image galleries with varying aspect ratios
  • Use for card feeds where content height varies (blog posts, testimonials, products)
  • Set columns to match the expected viewport width — 2 for narrow, 3-4 for wide
  • Combine with ResponsiveSwitcher to reduce columns on smaller screens
  • Use gap="md" for most card-based layouts; gap="sm" for dense image grids

When not to use

  • Do not use Masonry for uniform-height content — use a regular CSS grid or AspectGrid instead
  • Do not set very high column counts (>5) as it creates unreadably narrow columns
  • Do not expect left-to-right reading order — masonry flows top-to-bottom per column
  • Do not nest Masonry inside Masonry
  • Do not use for layouts that require precise item ordering — column flow is determined by height

Features

  • Pure CSS columns layout — zero JavaScript for masonry positioning
  • Configurable column count via the `columns` prop
  • Design-token-based gap spacing (sm, md, lg) for consistent rhythm
  • Vertical-pack flow fills shortest columns first for tight packing
  • Break-inside: avoid ensures children are never split across columns
  • Lightweight wrapper with no resize observers or layout calculations
  • CSS part: `grid` for targeted ::part() styling

API

columns number 3
Number of columns in the masonry grid. The browser distributes children across columns to minimize overall height difference.
gap 'sm' | 'md' | 'lg' 'md'
Spacing between columns and rows, mapped to design system spacing tokens (--space-sm, --space-md, --space-lg).
