- Using HTML `hgroup` (Deprecated vs. Modern Alternatives)
- hgroup has been deprecated and should not be used again. HTML5 once introduced hgroup to combine main and subtitles, but it has been removed from the specification and is an outdated tag; although it can still be recognized by modern browsers, it is no longer recommended. Alternatives include: 1. Use title tags (such as h1, h2) with paragraph tags p or div to achieve semantic structure; 2. Use header tags to wrap multiple titles to emphasize the head area; 3. Use Flexbox or Grid layout to improve visual effects. In actual development, we should focus on clear logic and clear hierarchy, avoid relying on specific tags to ensure better SEO and barrier-free access support, and choosing mainstream solutions is more conducive to maintenance and compatibility.
