This adds semantic meaning to the bottom footnotes organization and improves accessibility by aiding disabled users who rely on assistive devices such as screen readers which utilize semantic tags such as the footer element in order to navigate properly. The footer element also has a class “footnotes” to allow for any desired styling of the footnotes.
The implementation is a trivial change of two lines (insert the opening footer tag and closing) and I already have a pull request ready to go, but I want to make sure I’m permitted to submit a PR before I do so.
