Hiding text from the reading order
Prevent unwanted text being exposed to the reader by assistive technlogy
In some cases we want to show text in a visual publication that has no value or may be disruptive to the reader that is listening to the text being read or using a screen reader. A good example of this is running heads and page numbers which we may want to appear on multiple pages.
By using a Paragraph style whose name starts with the word 'HIDDEN' Circular Software will automtaically hide this from the reading order in the exported EPUB.

For those who like code… this is achieved by applying the aria-hidden="true" attribute to the container.
