Any other properties supplied will be spread to the root element (native element).

## CSS API

You can override all the class names injected by Material-UI thanks to the `classes` property.
This property accepts the following keys:


| Name | Description |
|:-----|:------------|
| <span class="prop-name">root</span> | Styles applied to the root element.
| <span class="prop-name">horizontal</span> | Styles applied to the root element if `orientation="horizontal"`.
| <span class="prop-name">vertical</span> | Styles applied to the root element if `orientation="vertical"`.
| <span class="prop-name">alternativeLabel</span> | Styles applied to the root element if `alternativeLabel={true}`.
| <span class="prop-name">completed</span> | Styles applied to the root element if `completed={true}`.

Have a look at [overriding with classes](/customization/overrides/#overriding-with-classes) section
and the [implementation of the component](https://github.com/mui-org/material-ui/tree/master/packages/material-ui/src/Step/Step.js)
for more detail.

If using the `overrides` key of the theme as documented
[here](/customization/themes/#customizing-all-instances-of-a-component-type),
you need to use the following style sheet name: `MuiStep`.
