The Knockout padding suite is built to anticipate needs across viewports & to adjust accordingly, so applying a viewport-specific modifier class should only be necessary when the intended behavior is exceptional. This means that, for instance, Padding - L may have 2 columns of left/right padding at desktop, & only a half column of padding at mobile. These behaviors can be adjusted on a per-project basis, but any adjustments should be made across all padding & margin classes in order to maintain consistency.
All classes convert to VW units above 1440px & to PX units at 1920px.
Tip: There are modifier classes for each viewport, but you must switch to tablet view to see tablet classes & mobile view to see mobile classes.
