Sapphire UIv4.1.0

Container

Constrain and centre a page’s content width. Use it to align sections and preserve a readable measure across large screens.

Examples

Padding

JSX usage

Install this example’s dependencies, load the package stylesheet from Setup, and add Example CSS where shown. The snippet includes its local helpers.

bun add @kongmy-dev/sapphire-ui react react-dom
"use client";
import { Container } from "@kongmy-dev/sapphire-ui/container";

function ContainerPadding() {
  return (
    <Container padding="lg">
      <p>Generous section padding</p>
    </Container>
  );
}

export default ContainerPadding;
Example CSS

Load these demo styles alongside the package stylesheet for the same layout and surfaces.

.docs-main {
  max-width: none;
}

.docs-container-frame {
  overflow: hidden;
  background: color-mix(in oklab, var(--background) 50%, transparent);
  border: var(--border-width) dashed
    color-mix(in oklab, var(--brand) 50%, transparent);
  border-radius: var(--radius-md);
}

.docs-container-frame--stacked {
  margin-top: var(--space-4);
}

.docs-container-demo {
  text-align: center;
  background: var(--background);
  outline: var(--border-width) dashed var(--border);
}

.docs-container-text {
  font-size: var(--text-sm);
  font-weight: 600;
  line-height: calc(var(--space-1) * 5);
  color: var(--muted-foreground);
}
HTML markup

Initial rendered HTML only. React handlers and portalled content require the JSX example; static HTML does not reproduce those interactions.

Setup

bun add @kongmy-dev/sapphire-ui react react-dom

For an app using package components throughout, load the full stylesheet once. Add this component import where you use it.

import "@kongmy-dev/sapphire-ui/sapphire.css";
import { Container } from "@kongmy-dev/sapphire-ui/container";

Mixing package and vendored components? Follow application setup.
