Props

Props of the native component are also available.

Name	Type	Default	Description
children	node		Used to render icon or text elements inside the AspectRatio if `src` is not set. This can be an element, or just a string.
color	'danger' \| 'info' \| 'neutral' \| 'primary' \| 'success' \| 'warning'	'neutral'	The color of the component. It supports those theme colors that make sense for this component. To learn how to add your own colors, check out Themed components—Extend colors.
component	elementType		The component used for the root node. Either a string to use a HTML element or a component.
maxHeight	number \| string		The maximum calculated height of the element (not the CSS height).
minHeight	number \| string		The minimum calculated height of the element (not the CSS height).
objectFit	'-moz-initial' \| 'contain' \| 'cover' \| 'fill' \| 'inherit' \| 'initial' \| 'none' \| 'revert-layer' \| 'revert' \| 'scale-down' \| 'unset'	'cover'	The CSS object-fit value of the first-child.
ratio	number \| string	'16 / 9'	The aspect-ratio of the element. The current implementation uses padding instead of the CSS aspect-ratio due to browser support. https://caniuse.com/?search=aspect-ratio
slotProps	{ content?: func \| object, root?: func \| object }	{}	The props used for each slot inside.
slots	{ content?: elementType, root?: elementType }	{}	The components used for each slot inside. See Slots API below for more details.
sx	Array<func \| object \| bool> \| func \| object		The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
variant	'outlined' \| 'plain' \| 'soft' \| 'solid' \| string	'soft'	The global variant to use. To learn how to add your own variants, check out Themed components—Extend variants.

The ref is forwarded to the root element.
