Fab API

The API documentation of the Fab React component. Learn more about the props and the CSS customization points.

Import

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

You can learn more about the difference by reading this guide.

The MuiFab name can be used for providing default props or style overrides at the theme level.

Name	Type	Default	Description
children*	node		The content of the button.
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
color	'default' \| 'inherit' \| 'primary' \| 'secondary'	'default'	The color of the component. It supports those theme colors that make sense for this component.
component	elementType	'button'	The component used for the root node. Either a string to use a HTML element or a component.
disabled	bool	false	If `true`, the button will be disabled.
disableFocusRipple	bool	false	If `true`, the keyboard focus ripple will be disabled.
disableRipple	bool		If `true`, the ripple effect will be disabled.
href	string		The URL to link to when the button is clicked. If defined, an `a` element will be used as the root node.
size	'large' \| 'medium' \| 'small'	'large'	The size of the button. `small` is equivalent to the dense button styling.
variant	'extended' \| 'circular' \| 'round'	'circular'	The variant to use. 'round' is deprecated, use 'circular' instead.

The ref is forwarded to the root element.

Any other props supplied will be provided to the root element (ButtonBase).

Rule name	Global class	Description
root	.MuiFab-root	Styles applied to the root element.
label	.MuiFab-label	Styles applied to the span element that wraps the children.
primary	.MuiFab-primary	Styles applied to the root element if `color="primary"`.
secondary	.MuiFab-secondary	Styles applied to the root element if `color="secondary"`.
extended	.MuiFab-extended	Styles applied to the root element if `variant="extended"`.
focusVisible	.Mui-focusVisible	Pseudo-class applied to the ButtonBase root element if the button is keyboard focused.
disabled	.Mui-disabled	Pseudo-class applied to the root element if `disabled={true}`.
colorInherit	.MuiFab-colorInherit	Styles applied to the root element if `color="inherit"`.
sizeSmall	.MuiFab-sizeSmall	Styles applied to the root element if `size="small"``.
sizeMedium	.MuiFab-sizeMedium	Styles applied to the root element if `size="medium"``.

You can override the style of the component thanks to one of these customization points:

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

The props of the ButtonBase component are also available. You can take advantage of this behavior to target nested components.
