                    FEATURES OF HTML

                  HTML has following features:
                    HTML is neither a word processing tool, nor a programming language, rather it is a markup language
                     that differs completely from the programming languages.

                     be a picture, text, sound and video clips.
                    HTML is a platform independent language i.e., HTML document can run on any type of operating
                     system or on any type of computer architecture like Macintosh computer, IBM computer, etc. HTML is
                     not case-sensitive.

                    HTML allows to format text, graphics, sound and video and save in an ASCll (American Standard Code
                     for Information Interchange) code.

                    HTML documents can contain links (called hyperlinks), this means a user can navigate from one page
                     to another as needed and can access and retrieve information from other sites.
                    PREREQUISITES TO WORK WITH HTML

                    Text Editor

                    Web Browser
                  Text Editor
