Before the mid1990s, the web was not much into a limelight. HTML was the major mean of web development. However in 1995, the National Center of Supercomputing Applications (NCSA) made advancements when they released the world’s first popular NCSA Mosaic Web Browser.
To challenge this, Marc Andreessen brought into another web browser called Mosaic Netscape and renamed it into Netscape Navigator.
For programmers it was difficult developing websites for both the Netscape Navigator and Microsoft’s Internet Explorer. So the quest started for developing cross platform websites.
