HTML Tabindex

What is HTML Tabindex?

The tabindex attribute in HTML is used to manage keyboard navigation by setting the order in which elements receive focus when the user presses the Tab key. This attribute is crucial for creating an accessible web experience, particularly for users who rely on keyboard navigation.

Basic Usage of Tabindex

The tabindex attribute can be applied to any focusable element. By default, elements like links, buttons, and form inputs are focusable. To make other elements focusable, you can use tabindex with positive, negative, or zero values.

Tabindex Values Explained

• Positive Values: Elements are focusable in the order of their tabindex values. This can disrupt the natural flow, so use sparingly.
• Zero: Elements are added to the natural tab order and are focusable. This is useful for custom focusable elements like divs or spans.
• Negative Values: Elements are focusable but are not included in the tab order. Useful for elements that should only be focusable programmatically.

Example of Using Tabindex for Custom Navigation

In the following example, we demonstrate how to use tabindex to create a custom navigation order:

Best Practices for Using Tabindex

• Prefer using tabindex="0" for adding non-interactive elements to the focus order without disrupting the natural flow.
• Avoid using positive tabindex values whenever possible as they can lead to confusing navigation experiences.
• Use negative tabindex values for elements that should be focusable via scripting, but not through keyboard navigation.
• Always test your focus order with a keyboard to ensure a logical and smooth user experience.
