# Button Appearance

The Button provides predefined appearance options such as different sizes, border radii, fill modes, and theme colors. If you omit an appearance property, the active Kendo theme supplies its default value.

Apart from the default vision of the Button, these alternative styling options enable you to configure each individual aspect of the appearance of a Button.

* [Fill Mode](https://www.telerik.com/kendo-angular-ui/components/buttons/button/appearance#fill-mode)
* [Theme Color](https://www.telerik.com/kendo-angular-ui/components/buttons/button/appearance#theme-color)

> Starting with [version 22.1.0](https://www.telerik.com/kendo-angular-ui/components/changelogs/kendo-angular-ui#v22.1.0), default values of the appearance properties are no longer hardcoded in the component. The default values are inherited from the Kendo theme.
