HTML attribute: crossorigin

-

The crossorigin attribute, valid on the <audio>, <img>, <link>, <script>, and <video> elements, provides support for CORS, defining how the element handles cross-origin requests, thereby enabling the configuration of the CORS requests for the element's fetched data. Depending on the element, the attribute can be a CORS settings attribute.

The crossorigin content attribute on media elements is a CORS settings attribute.

These attributes are enumerated, and have the following possible values:

anonymous

Request uses CORS headers and credentials flag is set to 'same-origin'. There is no exchange of user credentials via cookies, client-side TLS certificates or HTTP authentication, unless destination is the same origin.

use-credentials

Request uses CORS headers, credentials flag is set to 'include' and user credentials are always included.

""

Setting the attribute name to an empty value, like crossorigin or crossorigin="", is the same as anonymous.

An invalid keyword and an empty string will be handled as the anonymous keyword.

By default (that is, when the attribute is not specified), CORS is not used at all. The user agent will not ask for permission for full access to the resource and in the case of a cross-origin request, certain limitations will be applied based on the type of element concerned:

Element Restrictions
-img, audio, video - When resource is placed in <canvas>, element is marked as tainted.
script Access to error logging via window.onerror will be limited.
link Request with no appropriate crossorigin header may be discarded.

Note: The crossorigin attribute is not supported for rel="icon" in Chromium-based browsers. See the open Chromium issue.

Example: crossorigin with the <script> element

-
-

You can use the following <script> element to tell a browser to execute the https://example.com/example-framework.js script without sending user-credentials.

-

html

-
<script
-  src="https://example.com/example-framework.js"
-  crossorigin="anonymous"></script>
-
-
-
-

Example: Web manifest with credentials

-
-

The use-credentials value must be used when fetching a manifest that requires credentials, even if the file is from the same origin.

-

html

-
<link rel="manifest" href="/app.webmanifest" crossorigin="use-credentials" />
