网站代码优化全攻略：核心技巧与方法深度解析

〖One〗 Website code optimization is not just about making pages load faster; it directly impacts user experience, search engine rankings, and server resource consumption. The first and most fundamental layer of optimization focuses on reducing the number of HTTP requests, compressing assets, and leveraging content delivery networks. Every external resource—CSS files, JavaScript files, images, fonts, and favicons—triggers a separate request. Reducing these requests by combining files, using CSS sprites for small icons, and inlining critical CSS or JavaScript can dramatically shorten load times. For example, instead of loading ten separate CSS files, you can merge them into one minified file. Similarly, compressing images with modern formats like WebP or AVIF while maintaining acceptable quality cuts bandwidth by 30% to 60%. Gzip or Brotli compression on the server side shrinks HTML, CSS, and JavaScript files by 70% or more. A CDN distributes static assets across geographically dispersed servers, ensuring users fetch data from the nearest node, which reduces latency. Additionally, enabling HTTP/2 or HTTP/3 allows multiplexed connections, so multiple resources can be downloaded simultaneously without blocking. Cache headers like `Cache-Control` and `Expires` should be set aggressively for static files—typically for one year—so returning visitors avoid re-downloading unchanged resources. These baseline techniques are often low-hanging fruit that every website should implement before diving into deeper optimizations.

〖Two〗 Once the external resource pipeline is optimized, attention must turn to the code itself. Writing clean, semantic HTML not only benefits SEO but also reduces parsing time. Using modern HTML5 tags like `
