Message indicating
that the Web page
has passed the
validation
This page also provides you with some code and an image to display to tell the
world that your page validated. Print the browser view of this page to hand in to
your instructor.
You can also validate pages directly from the Web. Try validating the W3C's home
page at http://w3.org, Yahoo! at http://yahoo.com, and your school's home page. Visit
http://validator.w3.org and notice the Validate by URL area. Enter the URL of the
Web page you would like to validate in the Address text box. Click the Check button.
View the results. Experiment with the character encoding and doctype options. The
W3C's page should pass the validation. Don't worry if the other pages do not vali-
date. Validation is not required for Web pages. However, Web pages that pass the val-
idation should display well in most browsers. ( Note : If you have published pages to
the Web, try validating one of them instead of your school's home page.)
2. The Cynthia Says site offers free accessibility testing at http://www.cynthiasays.com
for your choice of Section 508 and WCAG 1.0 priority levels. Visit this site and test
your school's home page for Section 508 compliance. After the Section 508 accessi-
bility test is run, a report is displayed with categories corresponding to those listed
at http://www.access-board.gov/sec508/guide/1194.22.htm. Print the browser view
of the results page to hand in to your instructor. Were you surprised at the results?
Did you notice that some criteria, such as “Web pages shall be designed so that all
information conveyed with color is also available without color, for example from
context or markup,” cannot be checked automatically and must be verified manu-
ally by a person?
Next, check the Web page according to the W3C's WCAG 1.0 Priority 1 accessibil-
ity criteria. Run the test again and select the WCAG - Priority 1 criteria. After the
test is complete, a report is displayed with categories corresponding to those listed
at http://www.w3.org/TR/WCAG10/full-checklist.html. Print out the browser view
of the results page to hand in to your instructor.
Generally, it is easier to pass Section 508 validation than the WCAG 1.0 criteria.
Why do you think this is so? ( Note : If you have published pages to the Web, try
validating one of them instead of your school's home page.)
3. Deque offers the free Worldspace Online application at http://worldspace.deque.com.
Visit this site, select Accessibility Compliance Level WCAG 2.0 Level A, and test
your school's home page. After the test is run, a report is displayed that shows the
