Introduction to HTML
What is HTML?
HTML is a markup language. It involves placing
special instructions (known as tags in a plain text document,
to explain what the different parts of the document mean.
for example, to indicate a heading, you mark the text
that makes up a heading by a heading start tag, and a heading
stop tag. THe following illustrates a heading:
<H1>This is the heading </H1>
This is the heading
The tags plus the marked text is called an element. You can think of
a document as a collection of elements, each element defining part of the structure
of the document.
HTML and SGML
HTML is designed using a language called SGML... an extremely complicated system
for designing markup languages like HTML. Fortunately, you don't need to know
much about it!
