PDF Format Materials
All accessible PDF documents have the following five characteristics:
A logical structure and reading order
For screen readers to read a PDF document effectively, the document must have an
underlying logical structure and reading order. This logical structure and reading order
use behind-the-scenes elements called tags, which a PDF author adds to the document.
Tags define the intended reading order of the content on each page. Screen readers rely
on these tags to present text in a way that makes sense when someone is hearing the text
read out loud. The tags allow a screen reader to interpret page elements such as headings,
sidebars, tables, and multi-column text.
