For example, there is no need to install the Flash plugin in HTML5 as the element will run on its own.

The purpose of HTML5 is primarily to make it easier for web developers and browser creators to follow consensus-based standards, thereby improving compliance and enhancing compliance. It is also designed to provide a better, faster, and more consistent user experience for desktop and mobile visitors.

One of the design goals of HTML5 is to support multimedia on mobile devices. New syntax features have been introduced to support this functionality, such as video, audio and canvas tags. HTML5 also introduces new features that can truly change the way users interact with documents.
