Validation Errors

This section has a list of pages with validation errors. The code on each page is identical apart from the error. The hope is that you can see the following things:

  • You can judge if the error changes page layout in the browser (compare it to the valid page). Not all browsers will handle the same error in the same way.
  • You can see what a typical W3C error report for that mistake is (click the W3C link at the bottom of each page).
  • Eventually, there will be information on whether any of these errors stop search engine indexing. It is a bit early to know that yet.
