Don't WaitI used to think that my page had to be as perfect as possible before submitting it to the validator, as if Gerry Ostrovsky or one of the other people responsible for validating programs was examining my work. Scheduling the topic late in the semester may reinforce the impression that you do validating at the end. However, you can submit your work-in-progress and learn a lot about html that may help you finish the page. The validator programs are excellent tutors. These are computer programs, not humans, poring over your code, so you don't need to feel embarrassed about any mistakes and can submit the page again until you get it right. DOCTYPE mattersThe most authoritative is the W3C validator service at http://validator.w3.org/ The logo at the end of most pages in this class indicates that the code has passed this validator with no errors. If you get many error messages but are sure your code is not that bad, double check the DOCTYPE declaration and make sure it is typed exactly the way W3C asks for it to be typed. Check the doctype versions at W3C and, if necessary, cut and paste the definition for the Transitional version into your code to make sure your definition is letter-perfect. Once the validator recognizes your definition you may have fewer error messages. The validating service at Dr. HTML or at Web Mechanic may explain mistakes in a way that is more clear and helpful to you. These services will also check links to make sure they work, as well as spelling. Continue to "Other Checks" >> Other comment notes for this unit: |
