什么是<link>除了包括样式表之外，标签还可以做什么? [英] What does <link> tag do besides including stylesheets?
问题描述
我知道 HTML 标记用于附加样式表，但是查看 W3CSchools 标记参考，它的 rel 属性还有许多其他值.我已经找遍了所有地方，但我一生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如何运作.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途:
I know two prominent common uses:
使用
rel="stylesheet"引用外部 CSS 样式表
With
rel="stylesheet"to reference external CSS style sheets
使用 rel="favicon" 引用浏览器图标
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 中的链接文档有关样式表的详细信息，以及后两者.
Check the W3C Reference: Links in HTML documents for details on stylesheet, and the latter two.
