Core Web Vitals and Theming

Google's Core Web Vitals (LCP, FID, CLS) are heavily influenced by theme performance. A poorly structured theme can tank your scores regardless of your content quality.

Asset Loading Strategy

Learn how to defer non-critical CSS and JavaScript using theme settings or small code snippets. Only load scripts on the pages where they are actively required.

Image Optimization Integration

Ensure your chosen platform or theme has native support for modern formats like WebP and responsive image sizing (`srcset`). If not, implement a reliable lazy-loading solution.

Performance is the foundation upon which good design stands. Always test theme performance before launching a major visual overhaul.
