28 Sep 20233 minutes to read

The appearance of the Radio Button component can be customized by using the CSS rules. Define own CSS rules according to your requirement and assign the class name to the CssClass property.

The background and border color of the Radio Button is customized through the custom classes to create the primary, success, info, warning, and danger type of Radio Button.
