Shadcn Code Demo Block Three
Block Three removes the extra decorative frame and relies on its local CodeBlockIllustration. That illustration offers Next.js and Svelte tabs, uses CodeBlock for source display, and places a rendered LoginPage preview beside or below the code depending on container width.
Use this code demo when a product page needs to show implementation detail without becoming raw documentation. The source is a React client component with Tailwind CSS panel styling, and the syntax work is delegated to the local CodeBlock component.
The snippets are placeholders that post to https://api.example.com/data or render a sample login page. Replace them with real SDK calls, CLI usage, or framework examples before shipping the shadcn UI blocks article or page.
What to customize
- Replace placeholder snippets with working product code.
- Keep the language tabs aligned with what your audience actually uses.
- Check the panel height and masks after adding longer code.
Implementation notes
Is this only a screenshot?
No. The source renders interactive tabs and syntax-highlighted code inside the demo panel.
Where should this appear?
Use it near developer-focused product copy, docs CTAs, or a section explaining integration in a Next.js app.
