HTML Performance Optimization

HTML performance optimization is crucial for creating fast, responsive websites. It involves techniques to minimize load times and improve user experience.

Key Optimization Strategies

1. Minimize HTML Size

Reduce file size by removing unnecessary whitespace, comments, and formatting. This decreases load time and bandwidth usage.

2. Optimize Images

Use appropriate image formats and sizes. Implement HTML Responsive Images techniques to serve different image sizes based on device capabilities.

3. Leverage Browser Caching

Utilize caching headers to store static resources locally in the user's browser, reducing server requests on subsequent visits.

Code Examples

Example 1: Minified HTML

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Optimized Page</title></head><body><h1>Welcome</h1><p>This is an optimized HTML page.</p></body></html>

Example 2: Responsive Image

<picture>
  <source media="(min-width: 650px)" srcset="img-large.jpg">
  <source media="(min-width: 465px)" srcset="img-medium.jpg">
  <img src="img-small.jpg" alt="Responsive Image" style="width:auto;">
</picture>
