Introduction to Web Development • webpage – a document stored on a web server which can be accessed and viewed using a web browser on a computer or mobile device. • It can contain: • Graphics, audio and video. • Hyperlinks to other documents on the World Wide Web. • The content can be: • Static – content remains the same every time it is viewed. • Dynamic – content can change each time it is accessed based on how each viewer interacts with the content. • Website – a collection of related webpages.

  3. Purpose of a Website • A website is developed to build a relationship with a target audience and are created for the following reasons: • Sell – to sell products or services. • Advertises and/or demonstrates a product or service. • Provides customer support. • Often includes a database (or catalog) of products and services. • Examples: • Microsoft • Nike • http://www.michebag.com • Inform - provides information about a cause, event or organization and may provide tutorials or demonstrations. • Examples: • www.ncpublicschools.org • http://schoolcenter.gcsnc.com/nwhs • www.cnn.com

  4. Purpose of a Website • Entertain – provides information or links to movies, music, magazines, etc. • Examples: • www.itunes.com • www.imdb.com • Social – provides a network where people can interact online. • Examples: • www.facebook.com • www.youtube.com • Blogs • Wikis • Hybrid – a combination of any of the above. • Examples • www.ebay.com • www.petfinder.com

  5. What are web standards? • Basic set of rules for authoring and scripting languages used to make webpages. • Developed by the World Wide Web Consortium (W3C) and others.

  6. What is the W3C? • The W3C is a member organization. Some well known members include: • IBM • Microsoft • America Online • Apple • Adobe • Sun Microsystems

  7. The W3C and Web Standards • The W3C is working to make the web accessible to all users regardless of differences in: • Culture • Education • Ability • Resources • Physical Limitations

  8. Advantages of Standards • Helps ensure webpages display consistently in all browsers. • Internet Explorer, Mozilla Firefox, Opera, and other browsers display the website exactly the same way. • Faster website development. • Faster downloading of websites.

  9. Advantages of Standards continued • Equal access to information. • Differences in browser and/or operating system versions do not limit the user’s access to the site. • Differences in hardware do not limit the user’s access to the site. • Computer • PDA • Cell phone

  10. Disadvantages of Standards • Restricts development • Web authors who want to use new technologies are prevented from doing so. • Use of these technologies is discouraged because viewer’s computer systems may not be compatible with the software or hardware used by the new technologies. • The new technologies are not essential. • Slows innovation

  11. US Federal Agencies Must Provide: Equal access to and use of information on their websites for individuals and employees with disabilities. The information must be comparable to that provided to individuals and employees without disabilities. Applies ONLY to the United States. Section 508 Amendment to Rehabilitation Act
