Logo

Logo atom; the Digitaltableteur mark by default (monochrome currentColor, square footprint, optional controlled pulse), or any custom PNG/JPEG/SVG logo via src.

Status: stable. Group: display. Markdown version: /design-system/components/logo.md

When to use

The logo atom. Renders the Digitaltableteur mark by default; monochrome via currentColor so it inherits the surface's ink, square footprint. It renders only an svg or img and has no link prop; to make a home link, wrap it in a link. Pass src to render any custom logo image (PNG, JPEG, or SVG) inside the same square box.

When not to use

The contract records no forbidden uses.

Look-alikes

The contract names no look-alike with a deciding condition.

Props

Logo props
Prop	Type	Default	Description	Required
`src`	`string`	none	Optional image URL (PNG, JPEG, or SVG) rendered instead of the built-in Digitaltableteur mark. `title` becomes the alt text; `animated` and `background` apply to the built-in mark only and are ignored when `src` is set.	No
`size`	`number`	`24`	Square render box in pixels; any number works. Default 24. The size variant values (16, 24, 40, 64) are the recommended presets, not the only allowed values.	No
`animated`	`boolean`	`false`	Pulse the three leading bars while true; a controlled signal driven from the consumer's hover/focus state (respects prefers-reduced-motion). Default false.	No
`background`	`boolean`	`false`	Render the brand lime circle background behind a contrast mark (`--logo-background` / `--logo-color`). Default false.	No
`title`	`string`	`Digitaltableteur`	Accessible name for the mark. Ignored when `decorative`. Default "Digitaltableteur".	No
`decorative`	`boolean`	`false`	When true the mark is purely decorative and removed from the accessibility tree. Default false.	No
`className`	`string`	none	Optional utility/spacing classes.	No

Variants

Available sizes: 16, 24, 40, 64 (default 24).

Invalid combinations

SHOULD NOT: When src is set, then do not set animated or background. animated and background style the built-in mark only; with src set they are ignored.
SHOULD NOT: When decorative is true, then do not set title. A decorative logo is removed from the accessibility tree, so title is never announced. Drop title or make the logo non-decorative.

Keyboard

The contract records no keyboard interaction.

Rules

Every item under When not to use is a MUST NOT. MUST and SHOULD follow RFC 2119.

Logo rules
Level	Rule	How it is checked
SHOULD NOT	When `src` is set, then do not set `animated` or `background`. `animated` and `background` style the built-in mark only; with `src` set they are ignored.	Checked by the MCP tool validate_component_usage (rule `logo-src-ignores-mark-options`). Also enforced in code: Logo.tsx src branch returns before background/animated are applied.
SHOULD NOT	When `decorative` is `true`, then do not set `title`. A decorative logo is removed from the accessibility tree, so `title` is never announced. Drop `title` or make the logo non-decorative.	Checked by the MCP tool validate_component_usage (rule `logo-decorative-ignores-title`). Also enforced in code: Logo.tsx: title is not rendered when decorative.
MUST	ARIA: Accessible name via title unless decorative.	Not yet verified: no evidence record. WCAG 4.1.2.
MUST	ARIA: Decorative renders aria-hidden.	Not yet verified: no evidence record. WCAG 4.1.2.
MUST	Required stories produce no axe violations at the configured severity.	Automated by `npm run test:stories:matrix:ci`. WCAG 2.5.8.
MUST	The accessibility tree (role, name, state) matches the committed snapshot for every required story.	Automated by `npm run test:stories:matrix:ci`. WCAG 1.3.1, 4.1.2.
