Internationalization and localization require setting language attributes, using UTF-8 encoding, dynamically formatting content, and managing multilingual resources. 1. Set lang and xml:lang attributes to identify the page language; 2. Use UTF-8 encoding to avoid garbled code and ensure the server configuration is correct; 3. Use Intl objects or framework plug-ins to process related formats such as dates, currency, etc.; 4. Store multi-language content through JSON files, load and provide switching functions according to user preferences.

Use and tags to create accessible drop-down accordion effects without JavaScript; 2. Default content collapses, add open attributes to expand by default; 3. Custom styles can be customized through CSS, such as borders, backgrounds and custom arrows; 4. Multiple elements can be combined into a multi-panel accordion, which supports multiple openings by default, and JavaScript control is required; 5. Natively support screen readers and keyboard navigation, with strong semantics, and can achieve barrier-free access without ARIA. It is a lightweight, reliable and easy-to-implement solution.

Improve the core performance indicators of web pages (WebVitals) should start with optimizing the HTML structure, which includes the following points: 1. Reduce unnecessary DOM nodes, avoid excessive nesting, clean up discarded code, and use lightweight tags to shorten the parsing and rendering time; 2. Optimize the key rendering path, use key CSS inline, delay loading non-first-screen resources, and reasonably use async and defer to load scripts to speed up the first rendering; 3. Improve the interaction response speed, load key scripts as soon as possible, avoid a large number of inline scripts, and add loading="eager" to interactive elements; 4. Reasonably set meta tags and semantic structures, and use correct HTML tags and viewport settings.

Yes, you can create basic accordion effects with only HTML, which can be achieved through usage and tags; 1. Use as expandable container; 2. Use as clickable title; 3. Content is hidden by default and expand after clicking; 4. It can beautify styles with simple CSS; 5. No JavaScript required, semantic and highly accessible, and supports it in modern browsers, except for IE.

In web development, using HTML tags can effectively organize primary navigation and secondary navigation. 1. It is a semantic label that improves code readability and is conducive to SEO and barrier-free access; 2. The main navigation is used for the main entrance of the website, and secondary navigation is often used for internal links on the page; 3. Different navigation areas can be distinguished by aria-label or aria-labeledby attributes; 4. Different styles can be set for different use using class names or IDs in conjunction with CSS; 5. Pay attention to avoid abuse, optimize auxiliary functions, consider responsive design, and avoid nested use. Rational use can improve structural clarity and maintenance efficiency.
