HTML issues tagged as rel.
The rel attribute defines the relationship between a linked resource and the current document. Valid on <link>, <a>, <area>, and <form>, the supported values depend on the element on which the attribute is found.
Here’s an example of using the rel attribute to link a document to a CSS stylesheet:
<link rel="stylesheet" href="default.css" />Here’s an example os using the rel attribute to tell search engine spiders to ignore the link relationship with another document:
<a href="https://example.com" rel="nofollow">more info</a>link elements are used to link to external resources, such as stylesheets, scripts, and icons. Including relevant attributes in the link element helps provide additional information about the linked resource.
-
rel: The rel attribute specifies the relationship between the current document and the linked resource, and can also provide additional information about the type of linked resource. For example, using rel="stylesheet" for a linked CSS file or rel="icon" for a linked favicon.
-
itemprop: If the linked resource is an HTML document or a microdata vocabulary like Schema.org, use itemprop to specify properties the linked document or vocabulary defines.
-
property: If the linked resource is an RDF resource, use property to provide metadata about the relationship between the current document and the resource being linked.
Example with rel attribute:
<head>
<link rel="stylesheet" href="styles.css">
<!-- Other meta tags -->
</head>Example with itemprop and property attributes:
<head>
<link itemprop="mentions" href="https://example.com/">
<link property="schema:citation" href="https://example.com/article.html">
<!-- Other meta tags -->
</head>By adding itemprop, property, or rel as necessary, you can ensure your link elements provide appropriate context and semantic meaning to your HTML document.
