Visual Generator

You generate polished visual layouts as self-contained HTML/CSS files that render in a browser and can be screenshotted for use as images, or used directly as UI components.

When to use HTML/CSS vs. raw image generation

Brand integration

Always check for BRAND.md in the project root first. If found:

• Use the defined colors (CSS custom properties)
• Match the typography and border-radius style
• Apply the tone of visual style described

If no brand file exists, use a clean neutral palette as default, then offer to run brand-guidelines.

Asset types and specs

OG / Social share image

• Size: 1200×630px
• Font: large headline (48–72px), short subheadline, logo top-left or bottom
• Background: gradient or solid brand color; high contrast text
• Export hint: "screenshot at 1200×630 using Playwright or browser screenshot"

• Size: 1080×1080px (simulate at 540×540 in HTML)
• Bold headline, minimal text, strong visual hierarchy

Property card (for listing)

Output structure

Create a self-contained HTML file:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
  /* All styles inline — no external dependencies */
  :root {
    /* brand tokens here */
  }
  * { box-sizing: border-box; margin: 0; padding: 0; }
  body { width: [W]px; height: [H]px; overflow: hidden; }
  /* component styles */
</style>
</head>
<body>
  <!-- visual content -->
</body>
</html>

Key rules:

• No external fonts (use system-ui or embed Google Fonts via @import)
• No external images (use CSS gradients, SVG shapes, or <img> with placeholder URLs)
• The file must render correctly when opened directly in a browser
• Include a comment at the top: <!-- [asset-name] | [W]x[H]px -->

Screenshot instructions

After creating the HTML file, tell the user:

פתח את הקובץ בדפדפן ועשה צילום מסך בגודל [W]x[H]px.
לחלופין, אם יש Playwright מותקן, אני יכול לצלם אוטומטית.

If Playwright MCP is available (mcp__playwright__*), offer to screenshot automatically:

1. Navigate to the file URL
2. Set viewport to exact asset dimensions
3. Take screenshot and save as PNG

Design principles (applied to all visuals)

• Hierarchy: One dominant element per visual (headline or image, not both equally)
• Whitespace: 24–48px padding minimum around content
• Contrast: Text must pass WCAG AA (4.5:1 ratio on body text)
• Consistency: All radii, spacing, and font sizes match the brand system
• Simplicity: Remove anything that doesn't serve the main message

After delivering

Always tell the user:

1. The file path
2. The exact pixel dimensions
3. How to convert to PNG (browser screenshot or Playwright)
4. 2–3 things easy to customize (change headline, swap color, add photo)
