Typography

Use typography to present your design and content as clearly and efficiently as possible.

Introduction

The Typography component helps you maintain a consistent design by offering a limited set of values to choose while also providing a few convenient props that makes common designs faster to build. Joy UI's uses Public Sans, a Google Font, as the default typeface.

Component

After installation, you can start building with this component using the following basic elements:

import Typography from '@mui/joy/Typography';

export default function MyApp() {
  return <Typography>Hello world!</Typography>;
}

System props

As a CSS utility component, Typography supports every system properties.

<Typography textColor="neutral.500" fontSize="sm" fontWeight="lg">

Changing the semantic element

To control which HTML tag should be rendered in a given, one-off, situation, use the component prop.

{
  /* There is already an h1 in the page so let's not duplicate it. */
}
<Typography level="h1" component="h2">
  h1. Heading
</Typography>;

To control this in a much more efficient way, change the HTML mapping tags at the theme level.

const theme = extendTheme({
  components: {
    JoyTypography: {
      defaultProps: {
        levelMapping: {
          display1: 'h1',
          display2: 'h1',
          h1: 'h2',
          h2: 'h2',
          h3: 'h3',
          h4: 'h3',
          h5: 'h3',
          h6: 'h3',
          body1: 'p',
          body2: 'span',
          body3: 'span',
          body4: 'span',
          body5: 'span',
        },
      },
    },
  },
});

Levels

The Typography component has access to the typographic level scale defined in the theme. Use the level prop to control the scale value.

display1

display2

h1

h2

h3

h4

h5
h6

body1

body2

body3body4body5

Decorators

Use the startDecorator and/or endDecorator props to add supporting icons or elements to the typography.

The icon automatically adjusts to the scale

The display also changes to flexbox
123

Nested typography

Nested Typography components will render as a <span> tag by default, unless a value for the component prop in each component is specified.

<Typography>
  Paragraph by default.
  <Typography fontWeight="lg">I am a span</Typography> {/* render as <span> */}
  <Typography component="strong">but strong</Typography> {/* render as <strong> */}
</Typography>

Typography lets you create nested typography. Use your imagination to build wonderful user interface.

Create a new scale

To create your own typographic scale at the theme level, define the keys and values to theme.typography node.

extendTheme({
  typography: {
    subtitle: {
      fontSize: 'var(--joy-fontSize-lg)',
      fontWeight: 'var(--joy-fontWeight-md)',
      // CSS selector is also supported!
      '& + p': {
        marginTop: '4px',
      },
    },
    label: {
      fontSize: 'var(--joy-fontSize-sm)',
      fontWeight: 'var(--joy-fontWeight-lg)',
      lineHeight: 'var(--joy-lineHeight-lg)',
      marginBottom: '3px',
    },
  },
});

You can also access the newly created levels from the level prop.

<Typography level="subtitle">
<Typography level="label">

Remove the built-in scale

To start fresh with your own typographic scale, assign an undefined value to the built-in typography tokens in the theme.

extendTheme({
  typography: {
    h1: undefined,
    h2: undefined,
    h3: undefined,
    h4: undefined,
    h5: undefined,
    h6: undefined,
    body1: undefined,
    body2: undefined,
    body3: undefined,
    // ...your scale
  },
});

Make sure to remove them from the types as well if using TypeScript.

// in your theme or index file
declare module '@mui/joy/styles' {
  interface TypographySystemOverrides {
    display1: false;
    display2: false;
    h1: false;
    h2: false;
    h3: false;
    h4: false;
    h5: false;
    h6: false;
    body1: false;
    body2: false;
    body3: false;
    body4: false;
    body5: false;
  }
}
