Introduction

CSS3 is currently used to create impressive animations using keyframes and transitions. These animations allow you to create animated effects like fading, sliding, or rotating elements on your web pages.

When an event handler is triggered, JavaScript can be used to perform a variety of actions, such as changing the appearance of the element, displaying a message, or sending data to a server.
