Margin-right

Modals that are 36% width and larger have a margin-right: 20% (margin percentage is based off the width of the modal window). If the modal is smaller than 36% then it has a fixed margin-right: 16px/1rem. Body copy, including titles, in a modal always follows the 20% margin-right rule. However, inputs and other components may still expand to the full width of a modal window.

Margin-right for modals less than 36% (left) and greater than 36% (right).

Sizes

There are four modal sizes: xs, small, default, large. Each modal size has a responsive width that changes based on the browser size. As the browser decreases, the modal width percentage increases thus maintaining a proper ratio between the modal and browser. Modal widths are defined as percentages of the browser but will still align to columns on the 2x grid.

Max sizes

Each modal size has a max height and width in order to maintain a proper window ratio.

Mobile

On mobile devices, at the smaller break points the max-height does not apply. The height may either be 100% of the screen or maintain the height defined by the content while sticking to the bottom of the mobile screen.
