Answer 1

If you are using bootstrap-sass, then you can leverage input-size mixin:

$input-height-xs: 27px; // adjust it according to your theme.

@include input-size('.input-xs', $input-height-xs, $padding-xs-vertical, $padding-xs-horizontal, $font-size-small, $line-height-small, $input-border-radius-small);
