+Control Nonce Generation
+====================
+
+.. versionadded:: 4.8.0
+
+By default, both the script and style nonces are generated automatically. If you want to only generate one of them,
+you can set ``$enableStyleNonce`` or ``$enableScriptNonce`` to false in **app/Config/ContentSecurityPolicy.php**:
+
+.. literalinclude:: csp/016.php
+
+By setting one of these to false, the corresponding nonce will not be generated, and the placeholder will be replaced with an empty string.
+This gives you the flexibility to use nonces for only one type of content if you choose, without affecting the other.
