Comment on attachment 155459 [details] Patch 6 View in context: https://bugs.webkit.org/attachment.cgi?id=155459&action=review Ok, I agree with the design and the rough structure. Let's split this into multiple patches like: 1. Enable ENABLE_INPUT_TYPE_TIME_MULTIPLE_FIELDS and touch source files with ENABLE(INPUT_TYPE_TIME_MULTIPLE_FIELDS) (Only DateTimeFormat.h?) 2. WebCore/css/html.css part 3. WebCore/html/shadow/ part 4. WebCore/html/ part 5. RuntimeEnabledFeatures.cpp part > Source/WebCore/html/shadow/DateTimeFieldElements.h:88 > +class DateTimeNumericFieldElement : public DateTimeFieldElement { Please make its own source files. This class is not small. > Source/WebCore/html/shadow/DateTimeFieldElements.h:136 > +class DateTimeHourFieldElement : public DateTimeNumericFieldElement { ditto. > Source/WebCore/html/shadow/DateTimeFieldElements.h:153 > +class DateTimeSymbolicFieldElement : public DateTimeFieldElement { ditto.
Multiple fields time input UI is enabled for Chromium port, except for Android: http://trac.webkit.org/changeset/125868
