MapsIndoors Design Tokens (midt)

midt contains the MapsIndoors Design Tokens and tools to use them.

The tokes are compiled from JSON to SCSS mixins using Amazon's Style Dictionary, but you can use them as JSON objects or CSS classes too.

Install from npm using npm i -D @mapsindoors/midt@latest.

This repository uses main as the primary branch.

Use the SCSS mixins

Using the color-@mixin on a class in your CSS could look like this:

.test {
  @include color.red(60);
}

If you want to make the color a shade darker, increase the number:

.test {
  @include color.red(70);
}

You can use the same principles for applying padding or margin to an element like this:

.test {
  @include margin(xx-large);
  @include padding(small);
}

Or set the z-index:

.test {
  @include z-index(toast);
}

Use with SASS' @use function

SASS is moving away from explicitly @importing towards declaring what you want to @use instead:

@use 'color';

.test {
  @include color.red(60);
}
