on every page?
25
Should I attack this page by page?

Priority - Impact on User
• Critical - This type of accessibility error is a brick wall. Until this is fixed, there are significant barriers for a person with a disability to use this page.
• Serious - This is a very important accessibility error. It would be very frustrating to encounter this error and it might prevent some people with disabilities from using the page.
• Moderate - This is an accessibility error. It would be frustrating to encounter, but it would not prevent a person with a disability from using this page. (It might, however, make them decide to no longer use your site or services).
Minor - This is technically an accessibility error. It is unlikely to cause problems, but should be resolved to fully comply with the WCAG 2.0 AA standard.
