html - Wordpress 中的 rel ="generator"标签是什么意思？

Question

在我使用的 Wordpress 主题中，我在页脚中看到一行内容如下:

<a href="http://wordpress.org/" rel="generator">Proudly powered by WordPress</a>

在这种情况下，rel 标签有什么作用？

Answer 1

关于 rel 属性 MDN状态:

For anchors containing the href attribute, this attribute specifies the relationship of the target object to the link object. The value is a comma-separated list of link types values. The values and their semantics will be registered by some authority that might have meaning to the document author. The default relationship, if no other is given, is void. Use this attribute only if the href attribute is present.

W3.org添加:

Relationship between the document containing the hyperlink and the destination resource. The rel attribute has no default value. If the attribute is omitted or if none of the values in the attribute are recognized by the user agent, then the document has no particular relationship with the destination resource other than there being a hyperlink between the two.

因此，在您的情况下，该链接的 rel 属性表示(对某人)页面的生成器是 WordPress，并提供了一个提供给 WordPress.org 的链接。

不过您可能会注意到，generator 并未列为有效链接类型。这会在验证页面时导致错误:

Bad value generator for attribute rel on element a: The string generator is not a registered keyword.

因此，根据 HTM lvalidation 对您是否重要，您可能想要更改或删除该属性。
