Why Use SVG Placeholders
SVG placeholders are superior to external placeholder image services for development.
- Offline: SVG placeholders work without internet connection
- Custom size: any exact pixel dimension in one SVG
- No external request: eliminates HTTP call to placeholder service
- Branded: match your project's color scheme
- Inline: paste SVG directly in HTML — no separate file needed
Creating SVG Placeholders in Code
Simple SVG placeholder in one line of markup.
- Basic: <svg width='300' height='200' xmlns='http://www.w3.org/2000/svg'><rect width='100%' height='100%' fill='#ccc'/><text x='50%' y='50%' text-anchor='middle' dominant-baseline='middle' fill='#666'>300×200</text></svg>
- React component: const Placeholder = ({w,h,bg='#eee'}) => <svg width={w} height={h}><rect width='100%' height='100%' fill={bg}/></svg>
- Tailwind placeholder: combine SVG as data URI background-image with aspect-ratio utility class
- Next.js blur placeholder: convert small thumbnail SVG to base64 for next/image blurDataURL
