You can override the style of the component thanks to one of these customization points:

• With a rule name of the classes object prop.
• With a global class name.
• With a theme and an overrides property.

If that's not sufficient, you can check the implementation of the component for more detail.

Inheritance

The props of the Input component are also available. You can take advantage of this behavior to target nested components.
