What it is
Mantine is a modern React component library that provides over 100 fully featured components and hooks. It supports server-side rendering, dark theme, accessibility, and offers an extensive set of form and data display components.
Mantine provides components for inputs, navigation, overlays, typography, and data display. It also includes hooks for state management, responsiveness, and user interactions.

<>
<Modal opened={opened} onClose={() => setOpened(false)} title="Mantine Modal">
Modal content goes here
</Modal>
<Button onClick={() => setOpened(true)}>Open Modal</Button>
</>
);

The failures you are most likely to hit, and what actually resolves them.
- Styles not applied
- Ensure you have wrapped your app with `<MantineProvider>` and imported Mantine styles if necessary.
- Component not rendering
- Check that the correct package (`@mantine/core` or `@mantine/hooks`) is installed and imported.
- SSR hydration mismatch
- Use Mantine’s SSR setup guides when working with Next.js or Remix.
Best practices
- Wrap your application in MantineProvider to configure themes and global styles.
- Use Mantine hooks like `useDisclosure` and `useForm` to simplify state management.
- Take advantage of Mantine’s color schemes and dark mode support for better UX.
- Use Mantine’s Grid and Flex components for consistent layouts.
- Prefer Mantine’s built-in accessibility features instead of manually handling ARIA roles.
