When to use it​

In Content first: Article previews.

  • Use it when: A repeating unit of title, media and one destination or action.
  • Not when: Records people compare cell by cell (a table), or a whole card as one big link that screen readers read as one.

Instead:

  • Table: Records compared across rows.
  • Item: A compact row in a list.

How Content first uses it​

A card on the page
Use A border, no shadow
Not A strong shadow
Cards stay flat on the page; shadows are for floating things.

Words​

  • Write to one person: "you", not "users".
  • Short sentences with room to breathe.
  • Explain why before asking for anything.
  • Use: Read, Save for later, You, Next issue. Avoid: Click here, Submit, Users, Content.

The labels components use, from the voice tokens:

  • content.action.commit: Save
  • content.action.cancel: Not now
  • content.action.destroy: Remove
  • content.action.retry: Try again
  • content.action.empty-action: Browse guides

See Voice and tone for the whole voice.

Accessibility and keyboard​

Test before you ship:

  • One inner link or button names the destination; the rest is not one big link. undefined

Use it in code​

npx open-ds add card

The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.

Tokens it reads​

Card reads 17 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Card's tokens to change Card alone.

Changes with theme

Content first decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
