Iain works on the Web development team for a prominent community college system in the Southwest part of the United States. He was assigned to create several new Web pages, most of which would include detailed images. These images would aid navigation and provide vital registration instructions for the college students.

Iain was experienced with HTML and did not feel it was important to spend time validating all code because he was very busy. After creating and posting the new pages, however, Iain began receiving complaints from students who used text-based browsers. These students complained that they could not see (or hear) the registration instructions.To solve this problem, Iain added the alt attribute to each <img> tag to describe each image with text. Although it would have taken him more time to include the alt attribute in his initial page development, Iain found that the alt attribute resolved the complaints.

-Most people use browsers that support images. Why is it important to support all browser types in this situation?

-How could validation have saved Iain development time? What other advantages would have come from initial validation?

The Missing Link Omar works on a Web development team that just posted a site. This site contains both internal and external hyperlinks. Only three days after the site was posted to the production server, Omar found that four external hyperlinks were already invalid. To solve this problem, he checked each link manually and edited the HTML code to validate each one. After this experience, Omar wanted to manage the hyperlinks more closely and be notified of any problem links immediately. He obtained automatic link-checking software, which checks all site links periodically then sends an email reporting the status of every link. After installing this software, Omar was confident that his site's links would always remain valid.

-After Omar installs automatic link-checking software, will his site links always remain valid? Why or why not?

-Why would it be important to occasionally check your hyperlinks manually?

-Why would it be important to use both external and internal links on your Web site?
