HTML 5 is a correction of the Hypertext Markup Language (HTML), the official programming language for explaining the contents and appearance of Web pages. HTML5 was developed to solve agreement problems that affect the current standard, HTML4.
One of the common significant differences between HTML5 and previous versions of the rule is that older versions of HTML require restrictive plugins and APIs. HTML5 provides one standard interface to make loading components easier. For example, there is no want to install a Flash plugin in HTML5 because the element will run by itself. One of the design goals for HTML5 is to support for multimedia on mobile devices. New syntactic features were introduced to help this, such as video, audio and canvas tags.

HTML5 is the newest evolution of the standard that describes HTML. The term represents two various ideas. It is a new version of the HTML language, by new components, attributes, and behaviors, and a broader set of technologies that allow the building of more diverse and authoritative Web sites and applications. This set is seldom called HTML5 & friends and often shortened to just HTML5.
