Article Cover SVG Generation
Generate professional, visually striking article cover images in SVG format for technical blogs, documentation, and articles.
Critical Rules
- ViewBox Standard: Use
viewBox="0 0 1200 630"(social media friendly 1.91:1 ratio) - Text Readability (MUST follow):
- Main title: 44-48px, bold, high contrast - Subtitle: 28-32px, white or light color - Labels/tags: 14-16px - Never use fonts smaller than 11px
- Background Design:
- Always use gradient backgrounds (avoid flat solid colors) - Dark tech themes: #0d1117 → #161b22 (GitHub dark style) - Add subtle grid patterns or decorative elements for depth
- Visual Hierarchy:
- Title area: bottom 1/3 of the image (y: 420-540) - Diagram/illustration area: top 2/3 (y: 80-400) - Tags/labels: bottom edge (y: 550-600)
- Color Contrast: Ensure text is readable against backgrounds
- Light text on dark backgrounds - Use gradients for emphasis (orange/yellow for tech, blue/cyan for data)
Design Patterns
Tech Article Cover (Comparison Layout)
Best for: Performance comparisons, version upgrades, before/after scenarios

- Understand the article: What's the main topic? Is it a comparison, tutorial, or overview?
- Choose layout pattern:
- Comparison → Use 2-3 column comparison layout - Process/Flow → Use flow diagram layout - Single concept → Use centered illustration
- Extract key elements:
- Main title (keep concise, 10-15 Chinese chars or 5-8 English words) - Subtitle (descriptive, can be longer) - Key metrics (performance numbers, version info) - Tags (3-5 relevant keywords)
- Design the illustration:
- Use simple shapes (rectangles, arrows) - Show the core concept visually - Use color to differentiate states/versions
- Generate SVG: Follow the template, ensure all text is readable
Output
- Filename:
{article-slug}-cover.svg - Location: Same directory as the article or
assets/folder - Tell user: Can be opened in browser, converted to PNG via Inkscape/browser screenshot
Tips
- Chinese text: Use
font-family="Arial, sans-serif"which has good CJK support - Emphasis: Use
filter="url(#glow)"sparingly on key elements - Spacing: Keep 20-40px padding around text elements
- Testing: Open SVG in browser to verify rendering before finalizing
