//
// select
// textarea
// input[type="text"]
// input[type="password"]
// input[type="datetime"]
// input[type="datetime-local"]
// input[type="date"]
// input[type="month"]
// input[type="time"]
// input[type="week"]
// input[type="number"]
// input[type="email"]
// input[type="url"]
// input[type="search"]
// input[type="tel"]
// input[type="color"]

// This overrides the extra rounded corners on search inputs in iOS so that our

// In Mobile Safari, setting `display: block` on temporal inputs causes the
// text within the input to become vertically misaligned. As a workaround, we
// set a pixel line-height that matches the given height of the input, but only
// for Safari. See https://bugs.webkit.org/show_bug.cgi?id=139848
//
// Note that as of 8.3, iOS doesn't support `datetime` or `week`.
