## 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">flexContainer</span> | Styles applied to the flex container element.
| <span class="prop-name">centered</span> | Styles applied to the flex container element if `centered={true}` & `scrollable={false}`.
| <span class="prop-name">scroller</span> | Styles applied to the tablist element.
| <span class="prop-name">fixed</span> | Styles applied to the tablist element if `scrollable={false}`.
| <span class="prop-name">scrollable</span> | Styles applied to the tablist element if `scrollable={true}`.
| <span class="prop-name">scrollButtons</span> | Styles applied to the `ScrollButtonComponent` component.
| <span class="prop-name">scrollButtonsAuto</span> | Styles applied to the `ScrollButtonComponent` component if `scrollButtons="auto"`.
| <span class="prop-name">indicator</span> | Styles applied to the `TabIndicator` component.
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/Tabs/Tabs.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: `MuiTabs`.
