Specification https://www.w3.org/WAI/WCAG22/Understanding/target-size-minimum.html Design docs https://github.com/openui/open-ui/issues/1026 Summary The WCAG (accessibility guidelines) specify that the size of pointer inputs must be at least 24x24 CSS pixels. The <option> element within the <select> dropdown currently does not meet this height requirement. Blink component Blink>Forms>Select<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EForms%3ESelect> TAG review None TAG review status Not applicable Risks Interoperability and Compatibility Low risk. This update modifies the height of the <option> elements within the select popup to ensure WCAG standards are met. While this may lead to minor visual changes on websites, the overall impact remains minimal since it only alters the size of the popup and the height of each <option> element, without affecting the in-page controls. Gecko: Shipped/Shipping The default size of the <option> element within the <select> dropdown exceeds 24x24 CSS pixels. WebKit: No signal Filed bug https://bugs.webkit.org/show_bug.cgi?id=275079 Web developers: No signals Other signals: Ergonomics None Activation None Security None 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 (This question autogenerates the response "None" and the answer cannot be modified on Chrome Platform Status. To clarify, this change is considered low risk and carries the same compatibility risk for Android WebView applications as it does for other platforms) Debuggability None 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<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>? Yes WPT test is in progress: https://chromium-review.googlesource.com/c/chromium/src/+/5520310/39/third_party/blink/web_tests/external/wpt/html/semantics/forms/the-select-element/select-option-accessibility-minimum-target-size.html Flag name on chrome://flags None Finch feature name SelectOptionAccessibilityTargetSize Requires code in //chrome? False Tracking bug https://issues.chromium.org/issues/339141283 Estimated milestones Shipping on desktop 128 Shipping on Android 128 Shipping on WebView 128 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
