Button API

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

Import

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

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

Component name

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

Props

Name	Type	Default	Description

color	'default' | 'inherit' | 'primary' | 'secondary'	'default'	The color of the component. It supports those theme colors that make sense for this component.

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

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

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

Inheritance

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