Features#
On the surface, building a custom styled button seems simple. However, there are many
cross browser inconsistencies in interactions and accessibility features to consider.
Button
handles all of these interactions for you, so you can focus on the styling.
- Styleable – Hover, press, and keyboard focus states are provided for easy styling. These states only apply when interacting with an appropriate input device, unlike CSS pseudo classes.
- Accessible – Uses a native
<button>
element under the hood, with support for the Space and Enter keys. - Cross-browser – Mouse, touch, keyboard, and focus interactions are normalized to ensure consistency across browsers and devices.
Read our blog post about the complexities of building buttons that work well across devices and interaction methods to learn more.
Anatomy#
Buttons consist of a clickable area usually containing a textual label or an icon that users can click to perform an action. In addition, keyboard users may activate buttons using the Space or Enter keys.
If a visual label is not provided (e.g. an icon only button), then an aria-label
or
aria-labelledby
prop must be passed to identify the button to assistive technology.
Events#
Button
supports user interactions via mouse, keyboard, and touch. You can handle all of these via the onPress
prop. This is similar to the standard onClick
event, but normalized to support all interaction methods equally. In addition, the onPressStart
, onPressEnd
, and onPressChange
events are fired as the user interacts with the button.
Each of these handlers receives a PressEvent
, which exposes information about the target and the type of event that triggered the interaction. See usePress for more details.
function Example() {
let [pointerType, setPointerType] = React.useState('');
return (
<>
<Button
onPressStart={(e) => setPointerType(e.pointerType)}
onPressEnd={() => setPointerType('')}
>
Press me
</Button>
<p>
{pointerType
? `You are pressing the button with a
: !`'Ready to be pressed.'}
</p>
</>
);
}
function Example() {
let [pointerType, setPointerType] = React.useState('');
return (
<>
<Button
onPressStart={(e) => setPointerType(e.pointerType)}
onPressEnd={() => setPointerType('')}
>
Press me
</Button>
<p>
{pointerType
? `You are pressing the button with a
: !`'Ready to be pressed.'}
</p>
</>
);
}
function Example() {
let [
pointerType,
setPointerType
] = React.useState('');
return (
<>
<Button
onPressStart={(e) =>
setPointerType(
e.pointerType
)}
onPressEnd={() =>
setPointerType(
''
)}
>
Press me
</Button>
<p>
{pointerType
? `You are pressing the button with a
: !`'Ready to be pressed.'}
</p>
</>
);
}
Disabled#
A Button
can be disabled using the isDisabled
prop.
<Button isDisabled>Pin</Button>
<Button isDisabled>Pin</Button>
<Button isDisabled>
Pin
</Button>
Link buttons#
The Button
component always represents a button semantically. To create a link that visually looks like a button, use the Link component instead. You can reuse the same styles you apply to the Button
component on the Link
.
import {Link} from 'react-aria-components';
<Link className="react-aria-Button" href="https://adobe.com/" target="_blank">
Adobe
</Link>
import {Link} from 'react-aria-components';
<Link
className="react-aria-Button"
href="https://adobe.com/"
target="_blank"
>
Adobe
</Link>
import {Link} from 'react-aria-components';
<Link
className="react-aria-Button"
href="https://adobe.com/"
target="_blank"
>
Adobe
</Link>

Styling#
React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className
attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName
naming convention.
.react-aria-Button {
/* ... */
}
.react-aria-Button {
/* ... */
}
.react-aria-Button {
/* ... */
}
A custom className
can also be specified on any component. This overrides the default className
provided by React Aria with your own.
<Button className="my-button">
{/* ... */}
</Button>
<Button className="my-button">
{/* ... */}
</Button>
<Button className="my-button">
{/* ... */}
</Button>
In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:
.react-aria-Button[data-pressed] {
/* ... */
}
.react-aria-Button[data-pressed] {
/* ... */
}
.react-aria-Button[data-pressed] {
/* ... */
}
The className
and style
props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.
<Button
className={({ isPressed }) => isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>
<Button
className={({ isPressed }) =>
isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>
<Button
className={(
{ isPressed }
) =>
isPressed
? 'bg-gray-700'
: 'bg-gray-600'}
/>
Render props may also be used as children to alter what elements are rendered based on the current state. For example, you could render an extra element when the button is in a pressed state.
<Button>
{({isPressed}) => (
<>
{isPressed && <PressHighlight />}
Press me
</>
)}
</Button>
<Button>
{({isPressed}) => (
<>
{isPressed && <PressHighlight />}
Press me
</>
)}
</Button>
<Button>
{({ isPressed }) => (
<>
{isPressed && (
<PressHighlight />
)}
Press me
</>
)}
</Button>
The states, selectors, and render props for Button
are documented below.
Name | CSS Selector | Description |
isHovered | [data-hovered] | Whether the button is currently hovered with a mouse. |
isPressed | [data-pressed] | Whether the button is currently in a pressed state. |
isFocused | [data-focused] | Whether the button is focused, either via a mouse or keyboard. |
isFocusVisible | [data-focus-visible] | Whether the button is keyboard focused. |
isDisabled | [data-disabled] | Whether the button is disabled. |
Advanced customization#
Contexts#
All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).
Component | Context | Props | Ref |
Button | ButtonContext | ButtonProps | HTMLButtonElement |
This example shows a ButtonGroup
component that renders a group of buttons. The entire group can be marked as disabled via the isDisabled
prop, which is passed to all child buttons via the ButtonContext
provider.
import {ButtonContext} from 'react-aria-components';
interface ButtonGroupProps {
children?: React.ReactNode,
isDisabled?: boolean
}
function ButtonGroup({children, isDisabled}: ButtonGroupProps) {
return (
<div style={{display: 'flex', gap: 8}}>
<ButtonContext.Provider value={{isDisabled}}> {children}
</ButtonContext.Provider>
</div>
);
}
<ButtonGroup isDisabled>
<Button>Save</Button>
<Button>Publish</Button>
</ButtonGroup>
import {ButtonContext} from 'react-aria-components';
interface ButtonGroupProps {
children?: React.ReactNode;
isDisabled?: boolean;
}
function ButtonGroup(
{ children, isDisabled }: ButtonGroupProps
) {
return (
<div style={{ display: 'flex', gap: 8 }}>
<ButtonContext.Provider value={{ isDisabled }}> {children}
</ButtonContext.Provider>
</div>
);
}
<ButtonGroup isDisabled>
<Button>Save</Button>
<Button>Publish</Button>
</ButtonGroup>
import {ButtonContext} from 'react-aria-components';
interface ButtonGroupProps {
children?:
React.ReactNode;
isDisabled?: boolean;
}
function ButtonGroup(
{
children,
isDisabled
}: ButtonGroupProps
) {
return (
<div
style={{
display: 'flex',
gap: 8
}}
>
<ButtonContext.Provider
value={{
isDisabled
}}
> {children}
</ButtonContext.Provider>
</div>
);
}
<ButtonGroup
isDisabled
>
<Button>Save</Button>
<Button>
Publish
</Button>
</ButtonGroup>
Hooks#
If you need to customize things further, such as intercepting events or customizing DOM elements, you can drop down to the lower level Hook-based API. Consume from ButtonContext
in your component with useContextProps
to make it compatible with other React Aria Components. See useButton for more details.
This example uses Framer Motion to create an AnimatedButton
component that animates based on the isPressed
state provided by useButton
. It can be used standalone or as a part of any React Aria component.
import type {ButtonProps} from 'react-aria-components';
import {ButtonContext, useContextProps} from 'react-aria-components';
import {useButton} from 'react-aria';
import {motion} from 'framer-motion';
const AnimatedButton = React.forwardRef(
(props: ButtonProps, ref: React.ForwardedRef<HTMLButtonElement>) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] = useContextProps(props, ref, ButtonContext);
let { buttonProps, isPressed } = useButton(props, ref);
return (
<motion.button
{...buttonProps}
ref={ref}
animate={{
scale: isPressed ? 0.9 : 1
}}
>
{props.children}
</motion.button>
);
}
);
import type {ButtonProps} from 'react-aria-components';
import {
ButtonContext,
useContextProps
} from 'react-aria-components';
import {useButton} from 'react-aria';
import {motion} from 'framer-motion';
const AnimatedButton = React.forwardRef(
(
props: ButtonProps,
ref: React.ForwardedRef<HTMLButtonElement>
) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] = useContextProps(
props,
ref,
ButtonContext
);
let { buttonProps, isPressed } = useButton(props, ref);
return (
<motion.button
{...buttonProps}
ref={ref}
animate={{
scale: isPressed ? 0.9 : 1
}}
>
{props.children}
</motion.button>
);
}
);
import type {ButtonProps} from 'react-aria-components';
import {
ButtonContext,
useContextProps
} from 'react-aria-components';
import {useButton} from 'react-aria';
import {motion} from 'framer-motion';
const AnimatedButton =
React.forwardRef(
(
props: ButtonProps,
ref:
React.ForwardedRef<
HTMLButtonElement
>
) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] =
useContextProps(
props,
ref,
ButtonContext
);
let {
buttonProps,
isPressed
} = useButton(
props,
ref
);
return (
<motion.button
{...buttonProps}

animate={{
scale:
