Layout

NextUI's plugin provides a variety of layout customization options. Alter spacing units, font sizes, line heights, radius and more to personalize each theme to your liking.

Using layout tokens, you can ensure a uniform aesthetic across all components without needing to override the default Tailwind CSS configuration.

module.exports = {
  plugins: [
    nextui({
      layout: {}, // common layout options
      themes: {
        light: {
          layout: {}, // light theme layout options
          // ...
        },
        dark: {
          layout: {}, // dark theme layout options
          // ...
        },
        // ... custom themes
      },
    }),
  ],
};

Layout options are applied to all components.

Default Layout

Default values for the layout tokens are:

module.exports = {
  plugins: [
    nextui({
      layout: {
        spacingUnit: 4, // in px
        disabledOpacity: 0.5, // this value is applied as opacity-[value] when the component is disabled
        dividerWeight: "1px", // h-divider the default height applied to the divider component
        fontSize: {
          tiny: "0.75rem", // text-tiny
          small: "0.875rem", // text-small
          medium: "1rem", // text-medium
          large: "1.125rem", // text-large
        },
        lineHeight: {
          tiny: "1rem", // text-tiny
          small: "1.25rem", // text-small

          large: "1.75rem", // text-large
        },
        radius: {

            boxShadow: {
              // shadow-small
              small:
                "0px 0px 5px 0px rgb(0 0 0 / 0.02), 0px 2px 10px 0px rgb(0 0 0 / 0.06), 0px 0px 1px 0px rgb(0 0 0 / 0.3)",

          },
        },
      },
    }),

Units

Units tokens define consistent spacing, padding, margin, gap and sizes across the components. Based on the spacingUnit token (default 4px), NextUI auto-generates the following units:

// spacingUnit = 4px
{
  'unit-xs': '8px', // 2 * spacingUnit
  'unit-sm': '12px', // 3 * spacingUnit
  'unit-md': '16px', // 4 * spacingUnit
  'unit-lg': '22px', // 5.5 * spacingUnit
  'unit-xl': '36px', // 9 * spacingUnit
  'unit-2xl': '48px', // 12 * spacingUnit
  'unit-3xl': '80px', // 20 * spacingUnit
  'unit-4xl': '120px', // 30 * spacingUnit
  'unit-5xl': '224px', // 56 * spacingUnit
  'unit-6xl': '288px', // 72 * spacingUnit
  'unit-7xl': '384px', // 96 * spacingUnit
  'unit-8xl': '512px', // 128 * spacingUnit
  'unit-9xl': '640px', // 160 * spacingUnit
  'unit-0': '0px', // 0 * spacingUnit
  'unit-1': '4px', // 1 * spacingUnit
  'unit-2': '8px', // 2 * spacingUnit
  'unit-3': '12px', // 3 * spacingUnit
  'unit-3_5': '14px' // 3.5 * spacingUnit
  'unit-4': '16px', // 4 * spacingUnit
  'unit-5': '20px', // 5 * spacingUnit
  'unit-6': '24px', // 6 * spacingUnit
  'unit-7': '28px', // 7 * spacingUnit
  'unit-8': '32px', // 8 * spacingUnit
  'unit-9': '36px', // 9 * spacingUnit
  'unit-10': '40px', // 10 * spacingUnit
  'unit-11': '44px', // 11 * spacingUnit
  'unit-12': '48px', // 12 * spacingUnit
  'unit-13': '52px', // 13 * spacingUnit
  'unit-14': '56px', // 14 * spacingUnit
  'unit-15': '60px', // 15 * spacingUnit
  'unit-16': '64px', // 16 * spacingUnit
  'unit-17': '68px', // 17 * spacingUnit
  'unit-18': '72px', // 18 * spacingUnit
  'unit-20': '80px', // 20 * spacingUnit
  'unit-24': '96px', // 24 * spacingUnit
  'unit-28': '112px', // 28 * spacingUnit
  'unit-32': '128px', // 32 * spacingUnit
  'unit-36': '144px', // 36 * spacingUnit
  'unit-40': '160px', // 40 * spacingUnit
  'unit-44': '176px', // 44 * spacingUnit
  'unit-48': '192px', // 48 * spacingUnit
  'unit-52': '208px', // 52 * spacingUnit
  'unit-56': '224px', // 56 * spacingUnit
  'unit-60': '240px', // 60 * spacingUnit
  'unit-64': '256px', // 64 * spacingUnit
  'unit-72': '288px', // 72 * spacingUnit
  'unit-80': '320px', // 80 * spacingUnit
  'unit-96': '384px', // 96 * spacingUnit
}

Using Units

NextUI units behave like Tailwind CSS spacing units. You can use them in the margin, padding, width, height, min-width, min-height, gap, top, right, bottom, and left properties.

import {Button} from "@nextui-org/react";

export const MyButton = () => {
  return (
    <Button className="px-unit-2 py-unit-1 min-w-unit-3xl">
      My Button
    </Button>
  );
};

Remember: Any changes to the spacingUnit token will automatically update the units.

CSS Variables

NextUI creates CSS variables using the format --prefix-prop-name-scale for each layout token. By default the prefix is nextui, but you can change it with the prefix option.

module.exports = {
  plugins: [
    nextui({
      prefix: "myapp",
    }),
  ],
};

Then you can use the CSS variables in your CSS files.

/* With default prefix */
.my-button {
  padding: var(--nextui-spacing-unit-4);
  font-size: var(--nextui-font-size-small);
  line-height: var(--nextui-line-height-small);
  border-radius: var(--nextui-radius-medium);
}
/*  With custom prefix */
.my-component {
  padding: var(--myapp-spacing-unit-4);
  font-size: var(--myapp-font-size-small);
  line-height: var(--myapp-line-height-small);
  border-radius: var(--myapp-radius-medium);
}

API Reference
