+`<source>` can be any one of the values listed in [CSP Source Values](/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/Sources#sources).
 
-- `<host-source>`
-
-  - : Internet hosts by name or IP address, as well as an optional [URL scheme](/en-US/docs/Learn/Common_questions/What_is_a_URL) and/or port number. The site's address may include an optional leading wildcard (the asterisk character, `'*'`), and you may use a wildcard (again, `'*'`) as the port number, indicating that all legal ports are valid for the source.
-    Examples:
-
-    - `http://*.example.com`: Matches all attempts to load from any subdomain of example.com using the `http:` URL scheme.
-    - `mail.example.com:443`: Matches all attempts to access port 443 on mail.example.com.
-    - `https://store.example.com`: Matches all attempts to access store.example.com using `https:`.
-    - `*.example.com`: Matches all attempts to load from any subdomain of example.com using the current protocol.
-
-- `<scheme-source>`
-
-  - : A scheme such as `http:` or `https:`. The colon is required. Unlike other values below, single quotes shouldn't be used. You can also specify data schemes (not recommended).
-
-    - `data:` Allows [`data:` URIs](/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs) to be used as a content source. _This is insecure; an attacker can also inject arbitrary data: URIs. Use this sparingly and definitely not for scripts._
-    - `mediastream:` Allows [`mediastream:` URIs](/en-US/docs/Web/API/Media_Streams_API) to be used as a content source.
-    - `blob:` Allows [`blob:` URIs](/en-US/docs/Web/API/Blob) to be used as a content source.
-    - `filesystem:` Allows [`filesystem:` URIs](/en-US/docs/Web/API/FileSystem) to be used as a content source.
-
-- `'self'`
-  - : Refers to the origin from which the protected document is being served, including the same URL scheme and port number. You must include the single quotes. Some browsers specifically exclude `blob` and `filesystem` from source directives. Sites needing to allow these content types can specify them using the Data attribute.
-- `'unsafe-eval'`
-  - : Allows the use of `eval()` and similar methods for creating code from strings. You must include the single quotes.
-- `'unsafe-hashes'`
-  - : Allows enabling specific inline [event handlers](/en-US/docs/Web/Events/Event_handlers). If you only need to allow inline event handlers and not inline {{HTMLElement("script")}} elements or `javascript:` URLs, this is a safer method than using the `unsafe-inline` expression.
-- `'unsafe-inline'`
-  - : Allows the use of inline resources, such as inline {{HTMLElement("script")}} elements, `javascript:` URLs, inline event handlers, and inline {{HTMLElement("style")}} elements. The single quotes are required.
-- `'none'`
-  - : Refers to the empty set; that is, no URLs match. The single quotes are required.
-- `'nonce-<base64-value>'`
-
-  - : An allow-list for specific inline scripts using a cryptographic nonce (number used once). The server must generate a unique nonce value each time it transmits a policy. It is critical to provide an unguessable nonce, as bypassing a resource's policy is otherwise trivial. See [unsafe inline script](/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src#unsafe_inline_script) for an example. Specifying nonce makes a modern browser ignore `'unsafe-inline'` which could still be set for older browsers without nonce support.
-
-    > **Note:** The CSP `nonce` source can only be applied to _nonceable_ elements (e.g., as the {{HTMLElement("img")}} element has no `nonce` attribute, there is no way to associate it with this CSP source).
-
-- `'<hash-algorithm>-<base64-value>'`
-  - : A sha256, sha384 or sha512 hash of scripts or styles. The use of this source consists of two portions separated by a dash: the encryption algorithm used to create the hash and the base64-encoded hash of the script or style. When generating the hash, don't include the \<script> or \<style> tags and note that capitalization and whitespace matter, including leading or trailing whitespace. See [unsafe inline script](/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src#unsafe_inline_script) for an example. In CSP 2.0, this is applied only to inline scripts. CSP 3.0 allows it in the case of `script-src` for external scripts.
-- `'strict-dynamic'`
-  - : The `strict-dynamic` source expression specifies that the trust explicitly given to a script present in the markup, by accompanying it with a nonce or a hash, shall be propagated to all the scripts loaded by that root script. At the same time, any allow-list or source expressions such as `'self'` or `'unsafe-inline'` are ignored. See [script-src](/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src#strict-dynamic) for an example.
-- `'report-sample'`
-  - : Requires a sample of the violating code to be included in the violation report.
