Check out an example on CodeSandbox

import mq from "@dash-ui/mq";
import { styles } from "@dash-ui/styles";

// Creates the stored media queries
const breakpoint = mq(styles, {
  sm: "only screen and (min-width: 0em)",
  mq: "only screen and (min-width: 35em)",
  lg: "only screen and (min-width: 80em)",
});

// Can be used as a shortcut for `@media ...`
const boxOne = styles.one`
  width: 200px;
  height: 200px;

  /**
   * This box will be 400x400 when "md" breakpoint matches
   */
  ${breakpoint("md")} {
    width: 400px;
    height: 400px;
  }
`;

// Can be used like a style mapping
const boxTwo = styles.one(
  breakpoint({
    // This box will always have a `primary` color background
    default: ({ color }) => ({
      backgroundColor: color.primary,
    }),
    // This box will be 100x100 when `sm` media query is matched
    sm: {
      width: 100,
      height: 100,
    },
    // This box will be 200x200 when `md` media query is matched
    md: `
      width: 200px;
      height: 200px;
    `,
    // This box will be 400x400 when `lg` media query is matched
    lg: `
      width: 400px;
      height: 400px
    `,
  })
