If the value is a positive integer, the element will be included in sequential focus navigation and have a tab order preference relative to its value. If the value is 0, the element will be included in sequential focus navigation without being given special preference in the tab order. If the value is a negative integer, the element can be focused, but is not reached using sequential focus navigation. Three behaviors are defined for the tabindex attribute. This will allow the logical tab order to be maintained, while also dynamically correcting the reading order of the page. In such cases, focus can be sent via scripting to the relevant component, where that component's container element, or one of its child elements, has a tabindex value. Tabindex can also be used as a means to allow focus to be sent to components such as dialogs and menus, whose location in the DOM is not adjacent to their respective trigger controls. In such cases, the tab order can be set explicitly using the tabindex attribute for any element. The author may want to include non-interactive elements in the tab order. Furthermore, default tab order includes only interactive elements, such as form controls and links. In some cases, however, the author may want to specify a tab order which follows relationships in the content without following the reading order of the elements in the code. Explicitly setting tabindex values can easily introduce usability bugs. In such cases, it is preferable to use the default tab order and avoid explicitly setting tabindex values. Often, G59: Placing the interactive elements in an order that follows sequences and relationships within the content is sufficient to create a logical tab order. The objective of this technique is to provide a logical tab order in cases where the default tab order is not sufficient to meet the author's needs. Older browser versions might not support tabindex on non-focusable elements, nor a tabindex value less than 0.
