HTML Performance Tips
5 min read
Boost HTML performance: inline critical CSS, defer non-critical scripts, preload hero images, preconnect to third-party domains, lazy load below-fold images, and set explicit dimensions on all images.
HTML Performance
- Use
loading="lazy" on all below-the-fold images - Preload critical fonts:
<link rel="preload" as="font"> - Preconnect to third parties:
<link rel="preconnect" href="..."> - Use
defer on non-critical scripts - Minify HTML in production
- Use WebP or AVIF for images
- Set explicit width/height on images to prevent layout shift
