It may also be difficult for screen magnifier users, as the distance between reference and note can be considerable. However, for many screen reader users, glancing down the page and back will be impossible (obviously so if you can’t see the page at all). The assumption, of course, is that the reader can simply glance down a page from a footnote reference to the footnote itself and then back again. The problem is that a footnote can be separated from its reference (for example, a superscript “1”) by several paragraphs of text.
Defining the problemįrom an accessibility point of view, the most serious problem with footnotes is reading order (so too with endnotes, but the following will focus on footnotes only-endnotes will be addressed later). Fortunately, there is a better way, using some simple JavaScript to embed each note in a pop-up.
However, as will be seen, this approach is not ideal, for a number of reasons. They can be made more accessible by creating links from each note reference to its respective note and back again. 26 June 2017 | Ted Page Using JavaScript to enhance accessibilityįootnotes and endnotes in PDFs, whether created in Microsoft Word or Adobe InDesign, are not very accessible out-of-the-box.
