Failure of Success Criterion 3.2.3 due to presenting navigation links in a different relative order on different pages

ID: F66

Technology: failures

Type: Failure

When to Use

Applies to all technologies

Description

This describes a failure condition for all techniques involving navigation mechanisms that are repeated on multiple Web pages within a set of Web pages (Success Criterion 3.2.3). If the mechanism presents the order of links in a different order on two or more pages, then the failure is triggered.

Examples

Navigation presenting a series of links that are in a different relative order on two different pages

Examples of a navigation mechanism that presents links in a different order.

Page 1 navigation

<nav>
  <ul>
    <li><a href="brazil.html">Brazil</a></li>
    <li><a href="canada.html">Canada</a></li>
    <li><a href="germany.html">Germany</a></li>
    <li><a href="poland.html">Poland</a></li>
  </ul>
</nav>

Page 2 navigation

<nav>
  <ul>
     <li><a href="canada.html">Canada</a></li>
     <li><a href="brazil.html">Brazil</a></li>
     <li><a href="germany.html">Germany</a></li>
     <li><a href="poland.html">Poland</a></li>
  </ul>
</nav>

Tests

Procedure

  1. Check to see if a navigation mechanism is being used on more than one Web page.
  2. Check the default presentation of the navigation mechanism on each page to see if the list of links are in the same relative order on each Web page.

"Same relative order" means that secondary navigation items may be in between the link items on some pages. They can be present without affecting the outcome of this test.
