A footnote is an annotation with additional information usually provided at the end of a page, chapter, or book. We recommend avoiding footnotes because they aren't accessible and can present challenges for localization efforts.

Instead of a footnote, consider using the following formats to convey information:

If the only way to convey this information is to use a footnote, then use a symbol instead of a number. Use symbols in the following order:

  • *
  • #

Offset the symbol from the rest of the text with superscript—for example, <sup>‡</sup>.

For example, you can do the following:

Recommended: You want to add a footnote to this sentence.*

* Put this footnote at the bottom of the page.

Not recommended: You want to add a footnote.1
