When designing content for universal access it is essential to ensure that all users, such as individuals using voice navigation tools, can easily find their way through the content. One often overlooked aspect of accessibility is the use of alt text with table of contents entries.
A table of contents serves as a navigational guide, allowing them to find specific topics efficiently. For screen reader users, this structure becomes even more critical because it provides a navigational hierarchy. However, if the TOC entries are implemented using elements that lack meaningful semantic context, screen readers may announce them as unintelligible or meaningless items. This is where descriptive text alternatives play a vital role.
It's important to clarify that the term "alt text" specifically refers to image descriptions. For TOC entries, the correct accessibility approach involves leveraging native HTML semantics alongside ARIA enhancements. If a TOC entry includes an image or icon—including any visual indicator—that adds contextual information not present in the text, then that image must have a meaningful descriptive alternative. For example, if a TOC entry uses a small icon of a document next to the heading "Chapter 3: Data Analysis," the alt text for that icon should be minimal and unobtrusive, e.g., "Document indicator" or simply omitted if the text alone is sufficient. Avoid using alt text like "click here" or "link", which offers no meaningful information.
The primary method for making TOC entries accessible is to employ proper HTML structure. Each TOC item should be structured as a list item within an ketik decorative imagery. The real accessibility work lies in using semantic HTML, descriptive link text, proper ARIA attributes, and thorough testing. By ensuring that each item is unambiguous, well-organized, and functionally transparent, you enable everyone to access your material autonomously.
