What is HTML?

• Hypertext Markup Language (HTML) is the text
  markup language currently used on the World Wide
  Web
• It tells Web browsers how to structure and
  display Web pages

What is a Web Page?

• A text document containing information you wish
  to publish
• It has embedded instructions which determine how
  the document should be structured or presented
• They take the form of a start tag and possibly an
  end tag

What are tags?

•  In most cases, the tags come in pairs, each
  contained between angled brackets lt gt
• An example of ltbgtbold lt/bgt text.
• The ltbgt tag informs the browser where bold text
  will begin the lt/bgt tag indicates where this
  formatting ends. The result will look like this

Naming Web Pages

• An HTML file is just a plain text document with
  its file extension changed.
• To make one all you need is a basic text editor
  (like Notepad).
• When you come to save the file its name should
  take the form FILENAME.HTML instead of
  FILENAME.TXT.
• Each page within your site should be created as a
  separate text document.

12
Testing Web Pages

• Launch your browser
• Go to the File menu, select Open (or Open File if
  youre using Netscape Navigator) and locate the
  document that youve just created.
• Alternatively (double) click on the file icon in
  Windows
