Examples

Default button

This is the default variant for the Button component.

<Button>Default</Button>

<Button>Default</Button>

Danger button

The danger variant of Button is used to warn users about potentially destructive actions

<Button variant="danger">Danger</Button>

<Button variant="danger">Danger</Button>

Invisible button

The invisible variant of Button indicates that the action is a low priority one.

<Button variant="invisible">Invisible</Button>

<Button variant="invisible">Invisible</Button>

Different sized buttons

Button component supports three different sizes. small, medium, large.

<>
  <Button size="small">Search</Button>
  <Button sx={{mt: 2}}>Search</Button>
  <Button sx={{mt: 2}} size="large">
    Search
  </Button>
</>

<>
  <Button size="small">Search</Button>
  <Button sx={{mt: 2}}>Search</Button>
  <Button sx={{mt: 2}} size="large">
    Search
  </Button>
</>

Appending an icon

We can place an icon inside the Button in either the leading or the trailing position to enhance the visual context. It is recommended to use an octicon here.

<>
  <Button leadingVisual={SearchIcon}>Search</Button>
  <Button trailingVisual={SearchIcon} sx={{mt: 2}}>
    Search
  </Button>
  <Button leadingVisual={SearchIcon} trailingVisual={CheckIcon} sx={{mt: 2}}>
    Search
  </Button>
</>

<>
  <Button leadingVisual={SearchIcon}>Search</Button>
  <Button trailingVisual={SearchIcon} sx={{mt: 2}}>
    Search
  </Button>
  <Button leadingVisual={SearchIcon} trailingVisual={CheckIcon} sx={{mt: 2}}>
    Search
  </Button>
</>

Icon only button

A separate component called IconButton is used if the action shows only an icon with no text. This button will remain square in shape.

<IconButton aria-label="Search" icon={SearchIcon} />

<IconButton aria-label="Search" icon={SearchIcon} />

Different sized icon buttons

IconButton also supports the three different sizes. small, medium, large.

<>
  <IconButton aria-label="Search" size="small" icon={SearchIcon} />
  <IconButton aria-label="Search" icon={SearchIcon} sx={{ml: 2}} />
  <IconButton aria-label="Search" size="large" icon={SearchIcon} sx={{ml: 2}} />
</>

<>
  <IconButton aria-label="Search" size="small" icon={SearchIcon} />
  <IconButton aria-label="Search" icon={SearchIcon} sx={{ml: 2}} />
  <IconButton aria-label="Search" size="large" icon={SearchIcon} sx={{ml: 2}} />
</>

Button with counter

To show a count value as a trailing visual inside Button, pass a value to the count prop. The counter will match the variant styles of the parent button.

<Button count="1">Watch</Button>

<Button count="1">Watch</Button>

Block button

Use the block prop for full width buttons.

<Button block>Block</Button>

<Button block>Block</Button>

Props

Button

Name	Type	Default	Description
alignContent	'start' \| 'center'		Content alignment for when visuals are present.
as	React.ElementType	'button'	The underlying element to render — either a HTML element name or a React component.
block	boolean		Allow button width to fill its container.
children Required	React.ReactNode		The content of the button.
count	number \| string		For counter buttons, the number to display.
inactive	boolean		Whether the button looks visually disabled, but can still accept all the same interactions as an enabled button. This is intended to be used when a system error such as an outage prevents the button from performing its usual action. Inactive styles are slightly different from disabled styles because inactive buttons need to have an accessible color contrast ratio. This is because inactive buttons can have tooltips or perform an action such as opening a dialog explaining why it's inactive. If both `disabled` and `inactive` are true, `disabled` takes precedence.
leadingIcon Deprecated	React.ComponentType<OcticonProps>		An icon to display before the button text.
leadingVisual	React.ElementType		A visual to display before the button text.
loading	boolean		When true, the button is in a loading state.
loadingAnnouncement	string		The content to announce to screen readers when loading. This requires `loading` prop to be true
ref	React.RefObject<HTMLButtonElement>
size	'small' \| 'medium' \| 'large'	'medium'
sx	SystemStyleObject
trailingIcon Deprecated	React.ComponentType<OcticonProps>		An icon to display after the button text.
trailingVisual	React.ElementType		A visual to display after the button text.
variant	'default' \| 'primary' \| 'danger' \| 'invisible'	'default'	Change the visual style of the button.
labelWrap	boolean	false	Whether the button label should wrap to multiple lines of it is longer than the button width.
Additional props are passed to the `<button>` element. See button docs for a list of props accepted by the `<button>` element.
