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

```tsx
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](/theming/theme-object) styles.
By default, `Title` has no margins and paddings.
You can change `font-size`, `font-weight` and `line-height` per heading with [theme.headings](/theming/typography).

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](/theming/theme-object/)
- 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](https://developer.mozilla.org/en-US/docs/Web/CSS/text-wrap)
CSS property. It controls how text inside an element is wrapped.



You can also set `textWrap` on [theme](/theming/theme-object):

```tsx
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.


```ts
Title(_props)
```



```ts
export type TitleOrder = 1 | 2 | 3 | 4 | 5 | 6;

export type TitleSize = `h${TitleOrder}` | React.CSSProperties['fontSize'] | MantineFontSize;

export type TitleStylesNames = 'root';

export type TitleCssVariables = {
  root: '--title-fw' | '--title-lh' | '--title-fz' | '--title-line-clamp' | '--title-text-wrap';
};

export interface TitleProps
  extends BoxProps, StylesApiProps<TitleFactory>, ElementProps<'h1', 'color'> {
  /** Heading order (1-6), controls `font-size` style if `size` prop is not set @default 1 */
  order?: TitleOrder;

  /** Changes title size, if not set, then size is controlled by `order` prop */
  size?: TitleSize;

  /** Number of lines after which heading will be truncated */
  lineClamp?: number;

  /** Heading `text-wrap` CSS property @default 'wrap' */
  textWrap?: 'wrap' | 'nowrap' | 'balance' | 'pretty' | 'stable';
}

export type TitleFactory = Factory<{
  props: TitleProps;
  ref: HTMLHeadingElement;
  stylesNames: TitleStylesNames;
  vars: TitleCssVariables;
}>;

export type Mod = Record<string, any> | string;

export type BoxMod = Mod | Mod[] | BoxMod[];

export interface BoxProps extends MantineStyleProps {
  /** Class added to the root element, if applicable */
  className?: string | undefined;

  /** Inline style added to root component element, can subscribe to theme defined on MantineProvider */
  style?: MantineStyleProp;

  /** CSS variables defined on root component element */
  __vars?: CssVarsProp;

  /** `size` property passed down the HTML element */
  __size?: string;

  /** Breakpoint above which the component is hidden with `display: none` */
  hiddenFrom?: MantineBreakpoint;

  /** Breakpoint below which the component is hidden with `display: none` */
  visibleFrom?: MantineBreakpoint;

  /** Determines whether component should be hidden in light color scheme with `display: none` */
  lightHidden?: boolean;

  /** Determines whether component should be hidden in dark color scheme with `display: none` */
  darkHidden?: boolean;

  /** Element modifiers transformed into `data-` attributes, for example, `{ 'data-size': 'xl' }`, falsy values are removed */
  mod?: BoxMod;
}

export type ElementProps<
  ElementType extends React.ElementType,
  PropsToOmit extends string = never,
> = Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>;

export interface CSSProperties extends React.CSSProperties {
  [key: string]: any;
}

type MantineStyle = CSSProperties | ((theme: MantineTheme) => CSSProperties);

export type MantineStyleProp = MantineStyle | MantineStyle[] | MantineStyleProp[] | undefined;

export type CssVariable = `--${string}`;

export type CssVariables<Variable extends string = CssVariable> = Partial<Record<Variable, string>>;

export type CssVars<Variable extends string = CssVariable> =
  | CssVariables<Variable>
  | ((theme: MantineTheme) => CssVariables<Variable>)
  | CssVars<Variable>[];

export type CssVarsProp<Variable extends string = CssVariable> =
  | CssVars<Variable>
  | CssVars<Variable>[];
```


### 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.


```ts
Factory<{
  props: TitleProps;
  ref: HTMLHeadingElement;
  stylesNames: TitleStylesNames;
  vars: TitleCssVariables;
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<TitleFactory>
React.ElementType
Omit<React.ComponentProps<ElementType>, 'style' | PropsToOmit>
React.ComponentProps<ElementType>
ElementType
PropsToOmit
MantineFontSize
HTMLHeadingElement
```
