@leafygreen-ui/typography is a React component library that provides a set of typography components designed to align with MongoDB's design system. It allows developers to easily implement consistent and accessible typography styles in their applications.

What are @leafygreen-ui/typography's main functionalities?

Basic Typography

This feature allows you to use predefined typography components like H1 and Body to create headings and body text with consistent styling.


import { H1, Body } from '@leafygreen-ui/typography';

function App() {
  return (
    <div>
      <H1>Heading 1</H1>
      <Body>Body text goes here.</Body>
    </div>
  );
}

Customizing Typography

This feature allows you to customize the typography components by adding custom CSS classes to change their appearance.


import { H2, Subtitle } from '@leafygreen-ui/typography';

function CustomTypography() {
  return (
    <div>
      <H2 className="custom-heading">Custom Heading</H2>
      <Subtitle className="custom-subtitle">Custom Subtitle</Subtitle>
    </div>
  );
}

// CSS
.custom-heading {
  color: #4caf50;
}

.custom-subtitle {
  font-style: italic;
}

Responsive Typography

This feature demonstrates how to create responsive typography that changes based on the screen size using media queries.


import { H3, Overline } from '@leafygreen-ui/typography';
import { useMediaQuery } from 'react-responsive';

function ResponsiveTypography() {
  const isMobile = useMediaQuery({ maxWidth: 767 });

  return (
    <div>
      <H3>{isMobile ? 'Mobile Heading' : 'Desktop Heading'}</H3>
      <Overline>{isMobile ? 'Mobile Overline' : 'Desktop Overline'}</Overline>
    </div>
  );
}
