- Remove margin-bottom override in favor of .mb-0 utility class
- Apply the input line-height styles to match
- Remove the min-height to match the input
- Move disabled radio and checkbox styles to Reboot
- Collapse .radio and .checkbox into single class, .form-check
- Collapse .radio-inline and .checkbox-inline into single class, .form-check-inline
- Require classes for sub-elements in both new classes
- Rather than use CSS hacks, let's avoid needing to hack anything
- Creates a new Reboot entry to simply reset the appear of the temporal inputs, thereby avoiding the problem entirely
- Less than ideal for conveying affordance on iOS, but given bugginess of the input itself, seems a decent tradeoff
- Moves from no set line-height (inherited of 1.5) to declared 1.25 for
all inputs and buttons (regardless of size modifier).
- Updates padding to be `.5rem` instead of `.375rem` so that padding is
more likely to be whole numbers based on the root font-size.
- Whole numbers will be beneficial in avoiding odd fractional pixels
that can lead to misalignment as shown in #18607.
- Large buttons and inputs are now a tad wider, and smaller
buttons/inputs a tad shorter and narrower, too.
- Rename -height to -height-base to match other vars
- Drop use of -height across the board and rely on it to be inherited
- Adjust padding of .dropdown-header to account for different line-height of h6 heading element (this needs refactoring for variables and rems also)
Both widgets need to use the same border width because of input groups.
Thus:
$btn-border-width => $input-btn-border-width
$input-border-width => $input-btn-border-width
