Title

Install: npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1

Version and compatibility

Pinned Mantine Core 9.7.1 requires React and React DOM ^19.2.0 and matching @mantine/hooks@9.7.1, from the installed npm package's peerDependencies. Do not force it into React 18 or another incompatible version. Explain upgrade impact and agree on a plan with the project owner; do not hide conflicts with --force/--legacy-peer-deps. The native Provider enables theme.respectReducedMotion and uses forceColorScheme for light/dark.

Use case

Render a semantic heading with themed typography.

Native props used by this example

These props are extracted from the local typechecked JSX and grouped by their owning native component. This is not an exhaustive prop list; see pinned source signatures and inheritance below.

This minimal example passes children only; no additional props are invented. Optional props are in the source reference.

Interaction and state checks

Current scenarios: Default. Check actual behavior after selecting supported disabled/error/read-only scenarios; components without those native states do not receive invented universal props. Verify keyboard focus and exits, then connect changed values through the native callback signature.

Business integration boundary

Demo content/state is local, without server persistence, authorization or fetching. A static display component is not a completed business workflow.

Host setup

Install pinned @mantine/core and @mantine/hooks, import @mantine/core/styles.css at the entry and use MantineProvider. The example's theme/variant are JGuang-authored host props, not universal native component APIs; forceColorScheme synchronizes the app theme. Native implementation source is a reading reference: use npm exports rather than copying internal engines. This batch covers Core, not dates/charts/forms extension packages. Detailed upstream prose remains English.

Runnable usage

import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {

return <M.Title>Build something beautiful / 构建美好的界面</M.Title>;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

Preview states

Default

The example uses the native Mantine API. For supported input demos, change the local variant to Disabled, Invalid or Read only; these are example labels, not new component props. Keep the documented data, controlled values, stores and compound children when adapting the example.

Usage

Use the Title component to render h1-h6 headings with Mantine theme styles. By default, Title has no margins and paddings. You can change font-size, font-weight and line-height per heading with theme.headings.

Set the order prop to render a specific element (h1-h6); the default order is 1:

Size

You can change the Title size independent of its order:

  • If you set the size to h1-h6, then the component will add corresponding font-size and line-height from the theme
  • If you set the size to any other value, then line-height will be calculated based on order – size will impact only font-size

Text wrap

Use the textWrap prop to control the text-wrap CSS property. It controls how text inside an element is wrapped.

You can also set textWrap on theme:

import { createTheme, MantineProvider, Title } from '@mantine/core';

const theme = createTheme({
  headings: {
    textWrap: 'wrap',
  },
});

function Demo() {
  return (
    <MantineProvider theme={theme}>
      <Title>Some very long title that should wrap</Title>
    </MantineProvider>
  );
}

Line clamp

Set the lineClamp prop to truncate text after the specified number of lines:

Source-backed parameter reference

Implementation signatures and types are generated from the pinned local source. Optional props, native inherited types, union branches and never exclusions are preserved. A forwardRef implementation's ref is a React reference, not an additional business prop.

export type ElementProps<
  ElementType extends React.ElementType,

Native and external types

External types remain defined by React or native dependencies, not manually expanded into guessed props. The installed version's TypeScript definitions are authoritative.
