Install Snippet

The install-and-connect block of a developer page: client tabs, numbered steps, hard-edged dark code blocks, and a copy button that only says Copied when the clipboard really took it.

The prompt

Copy this text

Automatic copying is unavailable. Copy the selected text using your device’s copy command.

Written for the variant you picked above: Light

Build a developer quickstart block in a playful-technical, diagrammatic style: warm off-white page #f4efea, ink #383838, 2px ink borders, 2px corners, flat hard shadows, DM Mono uppercase for tabs, numbers and buttons, Inter light for prose. A row of joined folder-style tabs (Python, Node, CLI) sits on top of a white panel with a 4px 4px 0 hard shadow; the selected tab merges into the panel and carries a 6px yellow #ffde00 strip along its top edge, the others sit in the page colour with muted text. Inside, numbered steps: a 32×24 bordered number chip (sky #6fc2ff, then teal #16aa98 with white text, then coral #ff9538) beside a plain step title, then a dark #383838 code block with cream DM Mono 14px/1.65 text and a 2px border, horizontally scrollable without wrapping. Shell lines show a yellow '$ ' prompt that isn't selectable or copied; strings are pale amber and comments faint italic. A small outlined 'COPY' button sits in each block's top right: it fills teal and reads 'COPIED' only after navigator.clipboard.writeText resolves; if copying fails it fills coral, reads 'SELECTED', and selects the code so the reader can copy it themselves. Below 28rem the copy button sits above the code and the tabs share the width. Selected variant — Light (light): Light theme: page #f4efea, panel #ffffff, ink, borders and hard shadow #383838, muted #6f6a64, code blocks #383838 with #f4efea text and #a39e97 comments, yellow #ffde00, sky #6fc2ff, teal #16aa98, coral #ff9538. This selection takes precedence over references to other themes or options in the general brief. Implement this selected appearance; do not add a variant picker or alternative appearances unless requested. Implementation requirements: Use React and TypeScript. Keep the component self-contained, with uniquely scoped CSS and no animation libraries. Include required imports, styles and font setup in the result. Interaction: Tabs follow the tablist pattern: ←/→/Home/End move and select, one tab stop. With storageKey the chosen tab is remembered (wrapped in try/catch). Copy strips shell prompts. Copied and fallback states clear after 2.2 seconds. Motion: Only the copy button's fill changes, over 120ms. Reduced motion removes the transition. Accessibility: role=tablist/tab/tabpanel with aria-selected and aria-controls; code blocks are focusable so keyboard users can scroll them; copy buttons are named after their step; a hidden status line announces success or the fallback. Responsive behavior: Code scrolls sideways instead of wrapping; under 28rem the copy button moves above the code and tabs stretch evenly. Touch: Tabs and copy buttons are tap targets; long lines scroll with a swipe. Preserve keyboard access, visible focus and reduced-motion behavior. Keep fictional demo data and simulated service calls in a separate usage example; expose callbacks for real actions and recover from rejected requests. Keep usage-example links inside the demo: use local buttons or prevent navigation. Demonstration links must not navigate to Vitrine routes or open other pages; preserve real URL support in the reusable component itself. Verify the result at narrow and wide viewport sizes, with keyboard input and reduced motion enabled.

Notes
