The problem faced was that various clients would adapt different styles of their choice which might result in incompatibility over the wide spread users. There had to be standards adopted for attaining specific styles that could support the numerous requirements of the users. Thus the concept of style sheets had evolved.

Thus to differentiate them both the designer had to "mark-up" the specific styles for the codes to appear in the preferred fashion. Thus the Markup Languages came into existence.
