## CSS API

You can override all the class names injected by Material-UI thanks to the `classes` property.
This property accepts the following keys:
- `root`
- `horizontal`
- `vertical`
- `active`
- `completed`
- `alternativeLabel`
- `error`
- `disabled`
- `label`
- `iconContainer`
- `labelContainer`

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/StepLabel/StepLabel.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: `MuiStepLabel`.
