Font sizes#

You can adjust the font size of a heading with the fontSize prop:

Hello world

Editable example

Or, you can modify the font size for each heading level in the theme:

const theme = {
  Heading: {
    h1: {
      fontSize: '700'
    },
    h2: {
      fontSize: '600'
    },
    h3: {
      fontSize: '500'
    }
    h4: {
      fontSize: '400'
    }
    h5: {
      fontSize: '300'
    },
    h6: {
      fontSize: '200'
    }
  }
}
<Provider theme={theme}>
  ...
</Provider>

Responsive headers#

By default, each heading's font size will shrink in a mobile viewport.

You can modify the breakpoint in the component itself:

Hello world

Editable example

Or you can modify the breakpoint in the theme:

const theme = {
  Heading: {
    defaultProps: {
      shrinkBelow: 'desktop'
    }
  }
}
<Provider theme={theme}>
  ...
</Provider>

If you just want to disable shrinking, you can specify null:

const theme = {
  Heading: {
    defaultProps: {
      shrinkBelow: null
    }
  }
}
<Provider theme={theme}>
  ...
</Provider>
