Component-based approach has in last years shown considerable successes in many application domains. Distributed and web-based systems, desktop and graphical applications are typical examples of domains in which component-based approach has been very successful. In these domains the general-purpose component technologies, such as COM, .NET, EJB, J2EE are used.

The component model for the Web (also known as Web Components) consists of four pieces designed to be used together to let web application authors define widgets with a level of visual richness not possible with CSS alone, and ease of composition and reuse not possible with script libraries today.
These pieces are:
(i)Templates, which define chunks of markup that are inert but can be activated for use later.
(ii)Decorators, which apply templates to let CSS affect rich visual and behavioral changes to documents.
(iii)Custom elements, which let authors define their own elements, including new presentation and API, that can be used in HTML documents.
(iv)Shadow DOM which defines how presentation and behavior of decorators and custom elements fit together in the DOM tree.Both decorators and custom elements are called components.
