What is one of the significant functions of structured tags in document accessibility?

Structured tags play a crucial role in enhancing document accessibility by providing semantic meaning and establishing an appropriate hierarchy within the content. This is vital for assistive technologies, such as screen readers, which rely on these tags to interpret and convey the structure and organization of information to users who may have visual impairments. For instance, headings created with structured tags signal the importance of different sections, allowing users to navigate through the document more easily and understand the relationships between different pieces of content.

The semantic meaning provided by these tags helps to delineate various elements, such as paragraphs, lists, tables, and headings, which in turn facilitates a clearer understanding of the document’s purpose and content flow. As a result, structured tags are essential for ensuring that documents are not only accessible but also usable for individuals who depend on assistive technologies.
