- Scenario
- Creating accessible educational PDFs that contain embedded miniature pages from other editions.
- Observed behavior
- Deciding whether to tag the embedded miniature page as a single figure with alternative text or to apply complete structural accessibility tags to its internal content.
Evaluate the instructional purpose of the mini page to determine if screen-reader users need to interact with the full text or just understand the general context of the embedded page.
Applying the Correct Accessibility Tags to PDF Mini Pages
Determine the appropriate tagging method based on the depth of information the student needs to access from the embedded page.
Tagging an element as a figure is a critical information-access decision. When you use a figure tag, it limits screen-reader users exclusively to the alternative text you provide, hiding the internal text and logical structure of the mini page.
Review the miniature page to determine if the student needs to read all the specific information it contains, or if understanding a general summary is sufficient for the lesson.
If the miniature page serves only as a visual reference or high-level overview, tag the page as a 'Figure' and provide concise alternative text describing its purpose.
If the student must read, interact with, or extract specific information from the miniature page, apply full structural accessibility tags (such as headings, paragraphs, and lists) so screen readers can navigate the content properly.

Frequently Asked Questions
What happens when a PDF element is tagged as a figure?
When a PDF element is tagged as a figure, screen readers will announce it as an image and read the provided alternative text, completely skipping any actual text or structural elements located within that specific area.
Why shouldn't I use long alternative text for mini pages?
Screen readers read alternative text continuously without any structural pauses (like paragraphs or lists). This makes excessively long descriptions difficult for users to follow, retain, and comprehend.
Can I apply structural tags to an embedded image of a page?
If the mini page is inserted as a flat image (like a JPG or PNG), it does not contain readable text. You must either run OCR (Optical Character Recognition) to extract the text or manually recreate the text elements so they can receive proper structural accessibility tags.
When is complete tagging strictly required?
Complete structural tagging is required whenever the user needs to read, understand, or actively interact with the detailed text on the page, rather than just knowing that the page exists as a reference.
