Purging and Scanning
Tailwind's just-in-time engine is incredibly efficient, but you must ensure your content paths are correctly configured. In Next.js projects, always double-check that your app and components directories are included in the scan paths to avoid missing styles.
Minification and Compression
Standard CSS minification is essential, but you should also look into Brotli compression for your production assets. Since Tailwind generates repetitive class patterns, it compresses exceptionally well, often reaching over 90% compression ratios.
Lazy Loading Styles
For large applications, consider splitting your CSS. Tailwind v4 makes this easier by allowing you to define multiple entry points for different parts of your application, ensuring users only download the CSS they actually need for the current page.
