Base Card
Initial rules common to all cards. By default, a landscape ratio is enforced across all breakpoints. At sm and up, body content is docked to the bottom of container, at xs and below, it simply stacks underneath.
Landscape -> Square
Sets landscape ratio at xs, square at medium and above
Square -> Landscape
Sets square ratio, landscape at large and above
Portrait -> Landscape
Sets portrait ratio, landscape at large and above
Split Right
At sizes below medium, body content is reduced to 50% and docked to the right
Split left
At sizes below medium, body content is reduced to 50% and docked to the left
Split Right -> Square
Same as split right above, but resolves to square instead of landscape
Sticky
Body content is always absolutely positioned, even at smallest breakpoints (used in 3ups below)
