tabler/core/scss/tests/_media-breakpoint.test.scss

// Output tests for the responsive media-query mixins. Like the breakpoint
// functions, every mixin accepts an explicit `$breakpoints` map, so the tests
// pass a local fixture map and stay independent of the global `$grid-breakpoints`.
//
// `media-breakpoint-{up,down,between,only}` come from
// mixins/bootstrap/_breakpoints.scss; `media-breakpoint-down-than` lives in
// mixins/_functions.scss. Their names don't collide, so both are used as `*`.
//
// Max-widths are the breakpoint value minus 0.02px (the min-/max- overlap fix);
// the smallest/edge cases emit the content with no media query at all.

@use '../mixins/bootstrap/breakpoints' as *;
