# Box
<p class="description">The Box component is a generic, theme-aware container with access to CSS utilities from MUI System.</p>
{{"component": "@mui/docs/ComponentLinkHeader", "design": false}}
## Introduction
The Box component is a generic container for grouping other components.
It's a fundamental building block when working with Material UI—you can think of it as a `<div>` with extra built-in features, like access to your app's theme and the [`sx` prop](/system/getting-started/the-sx-prop/).
### Usage
The Box component differs from other containers available in Material UI in that its usage is intended to be multipurpose and open-ended, just like a `<div>`.
Components like [Container](/material-ui/react-container/), [Stack](/material-ui/react-stack/) and [Paper](/material-ui/react-paper/), by contrast, feature usage-specific props that make them ideal for certain use cases: Container for main layout orientation, Stack for one-dimensional layouts, and Paper for elevated surfaces.
## Basics
```jsx
import Box from '@mui/material/Box';
```
The Box component renders as a `<div>` by default, but you can swap in any other valid HTML tag or React component using the `component` prop.
The demo below replaces the `<div>` with a `<section>` element:
{{"demo": "BoxBasic.js", "defaultCodeOpen": true }}
## Customization
### With the sx prop
Use the [`sx` prop](/system/getting-started/the-sx-prop/) to quickly customize any Box instance using a superset of CSS that has access to all the style functions and theme-aware properties exposed in the MUI System package.
The demo below shows how to apply colors from the theme using this prop:
{{"demo": "BoxSx.js", "defaultCodeOpen": true }}
### With MUI System props
:::info
System props are deprecated and will be removed in the next major release. Please use the `sx` prop instead.
```diff
- <Box mt={2} />
+ <Box sx={{ mt: 2 }} />
```

## Anatomy
The Box component is composed of a single root `<div>` element:
```html
<div className="MuiBox-root">
<!-- contents of the Box -->
</div>
```
