<link> 是什么意思?标签除了包括样式表之外还做什么?
我知道 HTML <link> 标记用于附加样式表，但是查看 W3CSchools 标记参考，它还有许多其他的 rel 属性值.我找遍了所有地方，但我一辈子都找不到一个地方来详细描述其他价值观的作用以及它们的工作方式.谁能把我送到正确的地方或自己解释一下?
I know that the HTML <link> tag is used for attatching stylesheets, but looking at the W3CSchools tag reference, it has many other values for the rel attribute. I've looked all over the place, but I can't for the life of me find a place that describes in detail what the other values do and how they work. Can anyone send me to the right place or explain it themselves?
让我重新表述我的问题；我知道链接标签提供了与当前文档相关的其他页面，但它们是如何使用的?例如，如何使用 first、prev 和 next 关系?
Let me rephrase my question; I know that the link tag supplies other pages that relate to the current document, but how are they used? For example, how are the first, prev, and next relationships used?
推荐答案
我知道两个突出的常见用法:
I know two prominent common uses:
用
rel="stylesheet"来引用外部CSS样式表
With
rel="stylesheet"to reference external CSS style sheets
用rel="favicon"来引用浏览器的favicons
With rel="favicon" to reference browser favicons
另外还有
正向和反向链接 (
rel="next")
指向搜索引擎替代资源的链接 (rel="alternate")
Links to alternative resources for search engines (rel="alternate")
查看 W3C 参考:HTML 中的链接文档 以了解样式表和后两者的详细信息.
Check the W3C Reference: Links in HTML documents for details on stylesheet, and the latter two.
