Also called a layout engine, a rendering engine is used by a Web browser to render HTML pages, by mail programs that render HTML e-mail messages, as well as any other application that needs to render Web page content.
Web browsers[edit] To render a document such as an HTML page, most web browsers use an internal model similar to the DOM. The nodes of every document are organized in a tree structure, called the DOM tree, with topmost node named as Document object. When an HTML page is rendered in browsers, the browser downloads the HTML into local memory and automatically parses it to display the page on screen.
