Inheritance

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

Theme default props

You can use MuiBackdrop to change the default props of this component with the theme.

Slot name	Class name	Default component	Description
root	.MuiBackdrop-root	'div'	The component that renders the root.
transition	-	Fade	The component that renders the transition. Follow this guide to learn more about the requirements for this component.

These class names are useful for styling with CSS. They are applied to the component’s slots when specific states are triggered.
