Specification https://drafts.csswg.org/css-values-5/#request-url-modifiers Summary CSS url() functions accept optional request modifiers after the quoted URL string: cross-origin(), integrity(), and referrer-policy(). These modifiers control the fetch behavior of the referenced resource directly from CSS, without requiring changes to HTML markup or JavaScript. For example, background-image: url("image.png" cross-origin(anonymous)) fetches the image using CORS anonymous mode. This gives authors fine-grained control over cross-origin access, subresource integrity, and referrer policy for CSS-loaded resources including images, fonts, SVG references, and imported stylesheets. Blink component Blink>CSS Web Feature ID url-cross-origin, url-referrer-policy, url-integrity Motivation Web developers currently have no way to control fetch parameters for CSS-loaded resources. CSS URL request modifiers close this gap by allowing fetch parameters to be specified inline in any url() value, bringing CSS resource loading to parity with HTML resource loading. Initial public proposal No information provided TAG review No information provided TAG review status Not applicable Goals for experimentation None Risks Interoperability and Compatibility No information provided Gecko: No signal (https://github.com/mozilla/standards-positions/issues/1386) WebKit: Shipped/Shipping (https://developer.apple.com/documentation/safari-release-notes/safari-26_2-release-notes) Web developers: No signals Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? No information provided Debuggability No information provided Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?

Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
