Specimens for Design Systems

Leverage the wide variety of powerful React components of @lekoarts/gatsby-theme-specimens to build your design system. Display your colors, typography or any other design tokens with ease and focus on the design system itself, not on how to showcase it. Works seamlessly with MDX.

- Spacing scales
- Audio files and downloads
- border-radius or box-shadow
- Alerts to emphasize important messages

      options: {}
      }
    }
  ]
}

If you're already using Theme UI your theme file already has all necessary keys (styles, fontSizes, fontWeights, fonts). As you can see in the below example the theme.styles has entries like h1 which then will be used to display.

You can filter which keys to show by using the helper function filterStyles({ input, allowed }).

Editor

const theme = {
  fontSizes: [
    "0.875rem",
    "1rem",
    "1.25rem",
    "1.5rem",
    "1.875rem",
    "2.25rem",
    "3rem",
    "4rem",
    "4.5rem",
  ],
  lineHeights: {
    heading: "1.25",
  },
  fontWeights: {
    heading: "700",
  },
  fonts: {
    heading: "inherit",
  },
  styles: {
    root: {
      fontFamily: "body",
      lineHeight: "body",
      fontWeight: "body",

    a: {
      color: "primary",
      textDecoration: "none",

  },
};

render(
  <Heading

Sizes

Variant: tables.space

This theme also exposes a Table component. It is used in this case to showcase the different sizes of the theme. Generally speaking the Table component has the following props:

columns (string[])
titles (string[])
children (React.ReactNode)

The columns prop is defining the grid-template-columns of the table in the fashion of Theme UI (Responsive Styles). The titles should be the same count as columns.

So you can define the style for every breakpoint, e.g. [`120px 1fr`, `150px 1fr`] (120px for everything below the smallest breakpoint, 150px for everything above smallest breakpoint).

You can format the data you want to show how you like but in the end you should have the amount of columns as defined above.

Editor

const sizes = {
  0: "0",
  1: "0.25rem",
  2: "0.5rem",
  3: "0.75rem",
  4: "1rem",
  5: "1.25rem",
  6: "1.5rem",
  8: "2rem",
  10: "2.5rem",
  12: "3rem",
  16: "4rem",
};

render(
  <Table
    columns={[`120px 1fr`]}
    titles={[`Token`, `Value`]}
    className="sizes-table"
  >
    {Object.entries(sizes).map(([key, value]) => (
      <div key={key}>
        <div>{key}</div>
        <div>{value}</div>
      </div>
    ))}
  </Table>,
