Validation is a frequently requested enhancement. Clients ask me to add a W3C validation logo to their pages to indicate that they have employed a competent web designer. Validation enables web designers to take pride in their accurate coding. There are also practical reasons for validating, as follows:
  • Validating is another way to troubleshoot obscure problems. The designer can save time and avoid frustration by validating before testing a page in the various browsers.

  • It ensures that your pages are correctly coded so that browsers do not produce odd results.

  • It ensures that search engines will not be blocked by your minor coding errors.

  • Disabled users will be able to access your pages. Small coding errors can baffle an automated screen reader.

  • Mobile devices have reduced versions of the browsers; they cannot cope with the errors in non-validated sites.
