^ a b 'Behind the scenes of modern web browsers'.This can result in visual changes as more data is received, such as images being gradually filled in or a flash of unstyled content. Some engines may begin rendering before a page's resources are downloaded. The engine combines all relevant CSS rules to calculate the concrete graphical coordinates for the visual representation it will paint on the screen. For example, a published web page might use CSS to specify rules to style typography details, such as font, color, and text size.

Each style sheet is a series of rules which the browser engine interprets to determine how the document should be presented. The layout of a web page is typically specified by Cascading Style Sheets (CSS). Developer familiarity browser-based technologies has resulted in Electron and other cross-platform, browser engine-based application frameworks often being used in lieu of traditional GUI toolkits.

#CHROMIUM BROWSER ENGINE SOFTWARE#

The Electron framework, powered by Blink and V8 from Google's Chromium project, enables software developers to use technologies first created for the web platform-such as HTML, CSS, JavaScript, and the DOM-to create graphical desktop applications. For example, an email client might rely on a browser engine for displaying HTML email. Most development teams working on browser engines decouple development of the browser engine from development of the JavaScript engine that enables the browser to provide support for the language.īrowser engines are used in other types of programs besides web browsers. Although JS was initially created as a simple language for use on web pages, it is a general purpose language. In addition to layout and rendering, a browser engine enforces the security policy between documents, handles navigation through hyperlinks and data submitted through forms, and implements the Document Object Model (DOM) exposed to scripts associated with the document.Įvery significant web browser supports JavaScript (JS) to enable a wide range of interactive behavior specified by the publisher, however, JavaScript language support is treated as a separate concern, and browser vendors use a dedicated JavaScript engine to parse and evaluate JS. In practice, however, a given browser engine's rendering and layout components are tightly coupled and rarely encountered on their own outside the browser engine, unlike the case with browsers' scripting engines. In theory, layout and rendering (or 'painting') could be handled by different engines. The word ' engine' is an analogy to the engine of a car.īesides 'browser engine', two other terms are in everyday use regarding related concepts: ' layout engine' and ' rendering engine'. The primary job of a browser engine is to transform HTML documents and other resources of a web page into an interactive visual representation on a user's device.Ī browser engine is not a stand-alone computer program but rather a critical piece of a larger program, such as a web browser, from which the term is derived. ( Learn how and when to remove this template message)Ī browser engine (also known as a layout engine or rendering engine) is a core software component of every major web browser.
