+| <span class="prop-name">classes</span> | <span class="prop-type">object</span> |  | Override or extend the styles applied to the component. See [CSS API](#css) below for more details. |

+## CSS
+
+- Style sheet name: `MuiAlertTitle`.
+- Style sheet details:
+
+- `root`
+
+You can override the style of the component thanks to one of these customization points:
+
+- With a rule name of the [`classes` object prop](/customization/components/#overriding-styles-with-classes).
+- With a [global class name](/customization/components/#overriding-styles-with-global-class-names).
+- With a theme and an [`overrides` property](/customization/globals/#css).
+
+If that's not sufficient, you can check the [implementation of the component](https://github.com/mui-org/material-ui/blob/master/packages/material-ui-lab/src/AlertTitle/AlertTitle.js) for more detail.
