Built-in breakpoints allow you to easily build adaptive layouts.
Each breakpoint matches a fixed screen width. Values are min-width
based and apply when the screen width is equal or greater.
Most component size and layout props will accept an additional responsive object shape for modifying the given prop across breakpoints.
Each size maps to a corresponding key, the value of each will be applied when the screen size is greater than or equal to the named breakpoint.
