要查找完整的HTML屬性列表，應(yīng)參考WHATWG HTML Living Standard或W3C HTML5規(guī)範(fàn)，1. WHATWG文檔提供所有現(xiàn)代HTML認(rèn)可的全局和標(biāo)籤特定屬性；2. W3C文檔雖不如WHATWG更新頻繁，但同樣可靠；3. 全局屬性適用於所有元素，部分屬性僅限特定標(biāo)籤使用；4. 非標(biāo)準(zhǔn)屬性可能被瀏覽器支持但無法通過驗證；5. MDN Web Docs提供更易理解的屬性分類、用法說明及瀏覽器兼容性信息；6. 代碼編輯器如VS Code可通過自動補全輔助選擇屬性；7. 在線驗證工具如W3C Validator可檢查屬性是否標(biāo)準(zhǔn)；8. 注意部分屬性已過時或廢棄，如table的border、a標(biāo)籤的name、script的language；9. 自定義數(shù)據(jù)屬性（data-*）是合法且廣泛使用的；10. 查閱列表時需留意標(biāo)記以區(qū)分當(dāng)前有效與過時屬性，推薦WHATWG和MDN作為最清晰無冗餘的來源。

If you're looking for a complete list of all HTML attributes, the best place to start is the official documentation from the W3C or WHATWG. These are the standards bodies that define HTML, and their docs include comprehensive lists of global and tag-specific attributes.

Check the Official HTML Specifications

The WHATWG HTML Living Standard is considered the most up-to-date source for HTML specs. It includes every attribute recognized in modern HTML, both global (like class , id , style ) and specific to certain tags (like href for <a></a> or src for <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175121928568262.jpeg" class="lazy" alt="在哪裡可以找到所有HTML屬性的完整列表？" > ).

W3C's HTML5 specification page is another solid resource, though it's not as actively maintained as the WHATWG version. Either one will give you a full picture of what's valid in HTML today.

A few things to note:

• Global attributes apply to all elements.
• Some attributes only work on specific tags.
• Browsers often support non-standard attributes too, but they might not validate properly.

Use Developer-Friendly Reference Sites

If reading through formal specs feels overwhelming, sites like MDN Web Docs (Mozilla) offer more digestible explanations. MDN provides:

• A categorized list of common and less-used attributes
• Descriptions of where each can be used
• Browser compatibility notes

It's especially useful if you're trying to understand how to use an attribute rather than just listing them all out.

Other helpful tools:

• Code editors with HTML auto-completion (like VS Code) often show attribute suggestions based on context.
• Online validators like the W3C Validator can help check whether an attribute is standard and supported.

Keep in Mind: Not All Attributes Are Equal

While you can find long lists of attributes, some are obsolete or deprecated — meaning they used to be supported but shouldn't be used anymore. For example:

• border on <table> (use CSS instead)<li> <code>name on <a></a> anchors (replaced by id )
• language in <script></script> (now assumed to be JavaScript)

Also, custom data attributes ( data-* ) are valid and widely used in modern web development for storing extra info on elements.

So when browsing lists, look for flags or notes indicating whether an attribute is current or outdated.

基本上就這些。 If you want to stay accurate, stick to WHATWG or MDN — they're the clearest sources without unnecessary fluff.
