Analysis of rel attribute in HTML

Since I found that some classmates reposted and collected this article on Weibo, I went back to review this casually translated article. Later, I found that w3cschools.com.cn already has a corresponding Chinese translation, so I will continue to improve this article here to make it more valuable. The idea of ​​translating this document first came from the article http://vanessa.b3log.org/research-a-rel-value. I found that the rel attribute has many uncommon semantic values. The original article focused on listing the usage scenarios of these attribute values. I felt it was very necessary to understand the rel attribute in this way.

Links with the rel attribute:

<a rel="external" href="http://www.xxoo.com/">ooxx</a>

The rel attribute is supported by all major browsers.

注:瀏覽器渲染時會忽略此屬性,然而搜索引擎可以從它獲得更多的信息(a標簽僅在href屬性存在時有效)。

The rel attribute specifies the relationship between the current document and the linked document.

<a rel="value">

Deleted values: appendix, chapter, contents, copyright, glossary, index , section, start, subsection.

New values: archives, author, bookmark, external, first, index , last, license, nofollow, noreferrer, search, sidebar, tag,up.

由于本人水平有限,難免存在一些錯誤,看官們如果覺得有不妥或者需要補充的地方,請留言指出,謝謝!
