Backdrop API

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

Import

import Backdrop from '@material-ui/core/Backdrop';
// or
import { Backdrop } from '@material-ui/core';

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

Component name

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

Props

Name	Type	Default	Description
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.
invisible	bool	false	If `true`, the backdrop is invisible. It can be used when rendering a popover or a custom select component.
open^*	bool	false	If `true`, the backdrop is open.
transitionDuration	number \| { appear?: number, enter?: number, exit?: number }		The duration for the transition, in milliseconds. You may specify a single timeout for all transitions, or individually with an object.

The ref is forwarded to the root element.
Any other props supplied will be provided to the root element (Fade).

Inheritance

While not explicitly documented above, the props of the Fade component are also available on Backdrop. You can take advantage of this to target nested components.

CSS

Rule name	Global class	Description
root	.MuiBackdrop-root	Styles applied to the root element.
invisible	.MuiBackdrop-invisible	Styles applied to the root element if `invisible={true}`.

You can override the style of the component using one of these customization options:

With a rule name of the classes object prop.
With a global class name.
With a theme and an styleOverrides property.

If that isn't sufficient, you can check the implementation of the component for more detail.
