AppBar API

API documentation for the React AppBar component. Learn about the available props, and the CSS API.

Import

import AppBar from '@mui/material/AppBar';
// 或
import { AppBar } from '@mui/material';

You can learn about the difference by reading this guide on minimizing bundle size.

Component name

The name MuiAppBar can be used when providing default props or style overrides in the theme.

属性

Props of the Paper component are also available.

名称	类型	默认值	描述
children	node		The content of the component.
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
color	'default' \| 'inherit' \| 'primary' \| 'secondary' \| 'transparent' \| string	'primary'	The color of the component. It supports those theme colors that make sense for this component.
enableColorOnDark	bool	false	If true, the `color` prop is applied in dark mode.
position	'absolute' \| 'fixed' \| 'relative' \| 'static' \| 'sticky'	'fixed'	The positioning type. The behavior of the different options is described in the MDN web docs. Note: `sticky` is not universally supported and will fall back to `static` when unavailable.
sx	func \| object		The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.

ref 则会被传递到根元素中。
