The crossorigin attribute on a <link> tag specifies that CORS is supported when loading stylesheet or icon files from a third party server or domain.



A crossorigin attribute on a <link> element.
With this attribute, the link supports CORS. No credentials are sent when the stylesheet is retrieved.

<link crossorigin="anonymous" 
      rel="stylesheet" href="/tutorial/style.css">

Note: the example stylesheet is not retrieved from a third party server, but you get the idea.

Using crossorigin

The crossorigin attribute specifies that the link element supports CORS.

CORS stands for Cross Origin Resource Sharing.

CORS is a standard mechanism to retrieve files from a third party domain or server.

If specified, the stylesheet or icon file request will be sent with or without credentials.

Note:  This attribute is only relevant when the stylesheet or icon is retrieved from a third party server. Do not use this attribute when these files are on your own server.


<link crossorigin="anonymous | use-credentials">



Value Description
anonymous or "" or blank A cross-origin request will be sent without credentials and performs basic HTTP authentication. This is the default. Note: crossorigin="anonymous", crossorigin="", and crossorigin are all the same.
use-credentials A cross-origin request will be sent with credentials, cookies, and certificate.
