Rules
| Rule | Why | Check |
|---|---|---|
| A hub uses tiles or rows, never both. | One shape per list keeps scanning predictable. | Automated: tests/unit/site-system.test.ts |
API
| Prop | Type | Required | Default | What it does |
|---|---|---|---|---|
label | string | Yes | The section's accessible name. | |
tiles | list | No | Tiles (one of tiles or rows). | |
rows | list | No | Rows, for articles. | |
tail | html | No | A closing paragraph. | |
more | html | No | An arrow link after rows. |
Contract details
The full contract: identity, anatomy, variants, states, tokens, layout, motion, accessibility, content, tests
Identity
| Aspect | Value |
|---|---|
| Id | tile-grid |
| Layer | Templates |
| Category | section |
| Owner | Site system lead |
| Status | stable |
| Version | 1.0.0 |
| Source | apps/showcase/site/system/templates/tile-grid.ts (private repository; the contract and the render function are this one module) |
| Version | Date | Change |
|---|---|---|
| 1.0.0 | 2026-10-26 | Hub grid as one module: its markup moved out of the page builder (scripts/site) into the system. |
Use when
- Product, Solutions, Company, Demos and Articles hubs, and the 404 site map. Why: A hub's job is to send the reader to the right page.
Do not use when
- For related pages at the foot of a page. Why: Use the Related template: smaller and titled.
Anatomy
| Part | What it is |
|---|---|
| root | section.hub with aria-label |
| tiles | Tile set (fields-hub) or RowsList (rows-hub) inside a wrap |
| tail | div.prose.hub-tail after the tiles |
Made of: tile, rows-list, text, arrow-link.
Used in: page-articles, page-deep, page-hub, page-404.
Variants
| Variant | When | Why |
|---|---|---|
| tiles | Section hubs. | Colour doors into each page. |
| rows | Articles. | Many similar items scan better as rows. |
States
| State | Rendered or not applicable |
|---|---|
| default | default |
| hover | Not applicable: The hub grid is not interactive, so it has no hover state. |
| focus-visible | Not applicable: The hub grid does not take focus; links and buttons inside it carry their own focus ring. |
| active | Not applicable: The hub grid cannot be pressed. |
| disabled | Not applicable: The hub grid has nothing to disable. |
| loading | Not applicable: The hub grid is rendered at build time and is complete when the page loads. |
| empty | Not applicable: The hub grid is not rendered without content; the builder skips it. |
| error | Not applicable: The hub grid shows no data that can fail. |
| current | Not applicable: The hub grid has no current item. |
| visited | Not applicable: The hub grid is not a link. |
| expanded | Not applicable: The hub grid does not open or close. |
Tokens
| Part | Token |
|---|---|
| tail.color | --ink-2 |
Layout
| Aspect | Value |
|---|---|
| breakpoints | Required review at 390, 768, 1024 and 1440 px; execution is not implied by this declaration; columns stack under 768 px; the wrap keeps a 16 px gutter on phones. |
| wrapping | Text wraps; nothing scrolls sideways. |
| textExpansion | Japanese runs 20 to 40% longer; headings break between phrases (jaBreaks) and blocks grow downwards. |
Spacing and rhythm
| Aspect | Value |
|---|---|
| internal | One padding: --space-section-sm above and below (D-SITE-005). |
| external | Between the page head and the call to action. |
| rhythm | Cotton after the page head's edge. |
Motion
| Aspect | Value |
|---|---|
| None | No intrinsic element animation. The optional claude-entrance consumer profile may translate below-fold structure once (20px, --dur-weave, --ease-enter, --stagger); reduced motion disables it. This preserved baseline entrance is separate from element playback. |
Runtime and reuse
Render-only element; mount any registered child enhancements separately. Preserve required Site CSS, fonts, responsive and locale rules from nativeElement.
Accessibility passport
| Aspect | Value |
|---|---|
| role | region (section) named by its heading |
| name | Its h2, by aria-labelledby |
| keyboard | Links and buttons inside, in reading order. |
| focus | The --focus ring on every link and button inside. |
| screenReader | Read in source order; decorative weaving is aria-hidden. |
| contrast | Ink on cotton 14:1; text on every dye field 4.5:1 or better (checked by check-brand). |
| target | Links and buttons are 44 px tall. |
Content
| Slot | Length | Voice |
|---|---|---|
| label | 3 words | The section name |
Good: “All demos”
Bad: “Grid”
Japanese: Labels from nav-ja.
Icons and illustrations
None: this element uses no icon or illustration of its own.
Decisions and exceptions
Usage
17 uses across the built pages (measured by npm run site:system).
Tests
| Aspect | Value |
|---|---|
| unit | tests/unit/site-system.test.ts: renders every do and don't example through the registry and checks the classes it owns |
| visual | Not yet: there are no screenshot baselines; the Library page is checked for sideways scroll at 1440 px by tests/site/system.spec.ts |
| a11y | tests/site/system.spec.ts: axe (0 serious or critical) on the element's Library page in light and dark |
| parity | scripts/site/system/check.ts: Library examples are rendered by the same render function the site imports |
Figma
not-yet: The Loom Site Figma library is the last stage of the plan; this element is not mapped yet.
