Explainer None Specification https://drafts.csswg.org/css-values-5/#attr-notation Summary Implement the augmentation to attr() specified in CSS Level 5, which allows types besides <string> and usage in all CSS properties (besides pseudo-element 'content'). Example: <style> div { background-color: attr(data-foo type(<color>), red); } </style> <div data-foo="blue">test</div> Blink component Blink>CSS Search tags css, css-values, attr TAG review https://github.com/w3ctag/design-reviews/issues/513 TAG review status Pending Risks Interoperability and Compatibility No browser has implemented this feature yet. Even though there's no negative signals from other browsers, there's still a minimal interoperability risk that we end up the only implementation. There are also a few known cases where this advanced version behaves differently from the basic version in pseudo-element content property, which is a compatibility risk: - https://bit.ly/2XDhHtg - https://bit.ly/3grF3ur Gecko: No signal (https://bugzilla.mozilla.org/show_bug.cgi?id=435426) WebKit: No signal (https://bugs.webkit.org/show_bug.cgi?id=26609) Web developers: No signals Other signals: Security attr() can be used by injected CSS for data exfiltration. https://github.com/w3c/csswg-drafts/issues/5092 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? None Debuggability No additional DevTools support is needed. attr() function is inspectable in DevTools same way as any other CSS substitution function. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests? Yes https://wpt.fyi/results/css/css-values?label=master&label=experimental&aligned&q=attr Flag name on about://flags CSSAdvancedAttrFunction Finch feature name CSSAdvancedAttrFunction Requires code in //chrome? False Tracking bug https://bugs.chromium.org/p/chromium/issues/detail?id=246571 Estimated milestones Shipping on desktop 133 Shipping on Android 133 Shipping on WebView 133 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. 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).
