// Breakpoint viewport sizes and media queries.

// Breakpoints are defined as a map of (name: minimum width), order from small to large:

//    (xs: 0, sm: 576px, md: 768px, lg: 992px, xl: 1200px)
//
// The map defined in the `@grid-breakpoints` global variable is used as the `@breakpoints` argument by default.
