displayed through browsers such as Safari, Internet Explorer or
Mozilla Firefox. It provides a means to describe the structure
of text-based information in a document by denoting certain text
as headings, paragraphs, links etc and to supplement that text
with interactive forms, embedded images, and other objects. HTML
source code is used by the Web browser and typically not seen by
the user. The raw HTML can be viewed by choosing View Source
from the Web browsers view menu or by opening the HTML file in a
text editor. ||View other document file formats ||Any Web
