    Optimizing HTML for performance: Reducing DOM complexity.
    Reducing DOM complexity can improve web page performance, especially on mobile devices. The problem is that too many DOM nodes will increase memory usage, extend rendering time and slow down JavaScript execution.

Use semantic labels to replace meaningless divs; 3. Use Fragment to reduce hierarchy in component frameworks; 4. Review and control the impact of third-party scripts, detect the number of nodes through DevTools or Lighthouse, and delay loading non-critical scripts if necessary. The core is to keep HTML concise and effective, rather than blindly reducing the number of nodes.
