ViolaWWW was one of the first known web browsers for access to the World Wide Web and was developed for Unix and the X Window System in the early 1990s . ViolaWWW was favored by the European Organization for Nuclear Research (CERN) during this time .
Emergence
Viola was originally the invention of Pei-Yuan Wei , a student at the Experimental Computing Facility at the University of California , Berkeley. His interest in graphics-based software began with HyperCard , one of the first commercially available hypertext systems on a broad basis, with which he first came into contact in 1989. With the help of just one X terminal access and a HyperCard manual, Pei-Yuan Wei created the first version of Viola by taking over the existing concepts and implementing them for the X Window System.
Viola 0.8
In 1991 Viola 0.8 was released. A short time later, Viola 0.8 was used by O'Reilly Books , a technical publisher, to display and publish their Global Network Navigator website. In 1992, after a short further development, Viola was the first browser to contain or enable extended functions such as scriptable objects, style sheets and tables.
particularities
Viola had a toolkit, a tool for developing and supporting visual interactive media applications, which was based on a multimedia web browser application. Viola ran under the X Window System and could be used to add features such as applets and other interactive content to complex hypermedia applications built using HTML 3.0 (the latest version of HTML at the time) .
Viola was ahead of his time as he already received the following functions:
- Client-side integration of documents, forerunners of frames , or syndication via JavaScript , which is still widely used today
- A simple style sheet mechanism for overlaying information such as fonts, colors, and orientations in a document. Even before Cascading Style Sheets (CSS) was developed in 1998, Viola implemented these areas very well
- A sidebar panel for displaying meta information, navigation links, and other information similar to features found in today's modern browsers
- A scripting language that made it possible to embed interactive scripts and applets in an HTML document. This scripting language can be seen as a preliminary stage to today's JavaScript.
