Popular Web Designs

54 real-world design systems ready for use when generating HTML/CSS. Each template captures a site's complete visual language: color palette, typography hierarchy, component styles, spacing system, shadows, responsive behavior, and practical agent prompts with exact CSS values.

Related design skills

claude-design — use for the design process and taste (scoping a brief, producing variants, verifying a local HTML artifact, avoiding AI-design slop). Pair it with this skill when the user wants a thoughtfully-designed page styled after a known brand: claude-design drives the workflow, this skill supplies the visual vocabulary.
design-md — use when the deliverable is a formal DESIGN.md token spec file, not a rendered artifact.

How to Use

Pick a design from the catalog below
Load it: skill_view(name="popular-web-designs", file_path="templates/<site>.md")
Use the design tokens and component specs when generating HTML
Pair with the generative-widgets skill to serve the result via cloudflared tunnel

Each template includes a the agent Implementation Notes block at the top with:

CDN font substitute and Google Fonts <link> tag (ready to paste)
CSS font-family stacks for primary and monospace
Reminders to use write_file for HTML creation and browser_vision for verification

HTML Generation Pattern

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Page Title</title>
  <!-- Paste the Google Fonts <link> from the template's the agent notes -->
  <link href="https://fonts.googleapis.com/css2?family=..." rel="stylesheet">
  <style>
    /* Apply the template's color palette as CSS custom properties */
    :root {
      --color-bg: #ffffff;
      --color-text: #171717;
      --color-accent: #533afd;
      /* ... more from template Section 2 */
    }
    /* Apply typography from template Section 3 */
    body {
      font-family: 'Inter', system-ui, sans-serif;
      color: var(--color-text);
      background: var(--color-bg);
    }
    /* Apply component styles from template Section 4 */
    /* Apply layout from template Section 5 */
    /* Apply shadows from template Section 6 */
  </style>
</head>
<body>
  <!-- Build using component specs from the template -->
</body>
</html>

Write the file with write_file, serve with the generative-widgets workflow (cloudflared tunnel), and verify the result with browser_vision to confirm visual accuracy.

Font Substitution Reference

Most sites use proprietary fonts unavailable via CDN. Each template maps to a Google Fonts substitute that preserves the design's character. Common mappings:

Proprietary Font	CDN Substitute	Character
Geist / Geist Sans	Geist (on Google Fonts)	Geometric, compressed tracking
Geist Mono	Geist Mono (on Google Fonts)	Clean monospace, ligatures
sohne-var (Stripe)	Source Sans 3	Light weight elegance
Berkeley Mono	JetBrains Mono	Technical monospace
Airbnb Cereal VF	DM Sans	Rounded, friendly geometric
Circular (Spotify)	DM Sans	Geometric, warm
figmaSans	Inter	Clean humanist
Pin Sans (Pinterest)	DM Sans	Friendly, rounded
NVIDIA-EMEA	Inter (or Arial system)	Industrial, clean
CoinbaseDisplay/Sans	DM Sans	Geometric, trustworthy
UberMove	DM Sans	Bold, tight
HashiCorp Sans	Inter	Enterprise, neutral
waldenburgNormal (Sanity)	Space Grotesk	Geometric, slightly condensed
IBM Plex Sans/Mono	IBM Plex Sans/Mono	Available on Google Fonts
Rubik (Sentry)	Rubik	Available on Google Fonts

When a template's CDN font matches the original (Inter, IBM Plex, Rubik, Geist), no substitution loss occurs. When a substitute is used (DM Sans for Circular, Source Sans 3 for sohne-var), follow the template's weight, size, and letter-spacing values closely — those carry more visual identity than the specific font face.
