Foundation and layout

Container

Centered responsive content width.

Live example

A centered, narrow content container.

Usage

Each example includes the complete adapter-specific parameter reference. Copy it as a starting point, then remove options your use case does not need.

React

import { Container } from "@cofob/design-system-react";

/**
 * Complete Container parameter reference.
 * @param size
 *   type: "sm" | "md" | "lg" | "full" (React) · "narrow" | "default" | "wide" | "full" (Svelte)
 *   default: "lg" (React) / "default" (Svelte)
 *   example: "md"
 * @param children
 *   type: ReactNode | Svelte Snippet | child HTML
 *   default: —
 *   example: children / snippet / child HTML
 */
export function ContainerExample() {
  return (
    <Container>Content</Container>
  );
}

Svelte

<script lang="ts">
  import { Container } from "@cofob/design-system-svelte";

  // Complete Container parameter reference.
  // size
  //   type: "sm" | "md" | "lg" | "full" (React) · "narrow" | "default" | "wide" | "full" (Svelte)
  //   default: "lg" (React) / "default" (Svelte)
  //   example: "md"
  // children
  //   type: ReactNode | Svelte Snippet | child HTML
  //   default: —
  //   example: children / snippet / child HTML
</script>

<Container>Content</Container>

Contract

CSS selector	`.cf-container`
Adapters	Native · React · Svelte
Primary props	size · children
Documented states	default · hover/focus where interactive · disabled where applicable
Interaction	Static and SSR-safe
Theme	Semantic light and dark tokens

Composition

Native attributes and framework props are forwarded. Add custom classes without replacing the semantic contract.

Parameters

Adapter differences are explicit. Native element attributes are forwarded in React and Svelte and can be written directly in HTML.

Parameter	Type	Default	Adapters	Example	Description
`size`	`"sm" \| "md" \| "lg" \| "full" (React) · "narrow" \| "default" \| "wide" \| "full" (Svelte)`	`"lg" (React) / "default" (Svelte)`	React · Svelte · HTML	`"md"`	Applies a design-system size token.
`children`	`ReactNode \| Svelte Snippet \| child HTML`	`—`	React · Svelte · HTML	`children / snippet / child HTML`	Idiomatic adapter composition content.
