For questions about development of games to be played in an Internet browser.

Web browser (or often called just 'browser') is an application for retrieving, presenting and traversing information resources on the WWW (the Internet). An information resource is identified by a URI and may be a web page, image, video or other piece of content.

With rise of the HTML5 standard browsers become a popular game development solution, partially because of their natural cross-platform support and thus, high availability to user.
