12.8 On each web page, is the navigation sequence consistent?

Test 1 (12.8.1)

1. Tab forward (Tab key) and backward (Shift+Tab key) through all the content in the document.
2. Check that the order in which the focus is moved is consistent with the content in question (for example, the navigation sequence in a modal window should only consider the interface elements present in this window).
3. If this is the case, the test is validated.

Note: the navigation sequence does not have to follow the natural reading order (left to right and top to bottom, for example) as long as the elements are accessible in a coherent order.

Test 2 (12.8.2)

1. Find all the content inserted in the document using a script (display hidden elements, update content using AJAX for example).
2. Position the tab on the trigger element and activate it.
3. After displaying the updated content, check that the navigation sequence remains consistent (correct repositioning of the focus).
4. If this is the case, the test is validated.
