Overview

• This is a quick overview of the tools available
  for web site construction and maintenance and
  where to get them inexpensively
• We will also look at where the web is going and
  what open source means
• Security is a primary concern both in the sense
  of protecting personnel from attacks and as far
  as keeping your own computer safe while it is on
  the Internet.

Development Tools

• There is no one way, right way, wrong way, bad
  way, or great way to construct a web page or web
  site.
• Primary methods
• Hand-code the HTML and other languages
• Use an editor
• Use an online support tool that takes the
  programming out of the creation of the web site
• Leads to a focus on content and not form

Think of the Web Page

• Think of the web page as two different components
• Content
• Layout
• As web master do you want to be responsible for
  content or layout?
• The novice web master wants to be in charge of
  both
• The experienced web master knows that it is best
  to offload content development and focus on
  layout and functionality
• What do you start with?
