|

* OPTIONAL LINK ELEMENT FOR FOOTNOTE REFERRERS AND BACKLINKS
|
||
*
|
||
* STYLING:
|
||
* Link color is preferred for referrers and backlinks.
|
||
* Setting a global link color is a common feature in WordPress themes.
|
||
* CSS does not support identifiers for link colors (color: link | hover | active | visited)
|
||
* These are only supported as pseudo-classes of the link element.
|
||
* Hence the link element must be present for styling purposes.
|
||
* But styling these elements with the link color is not universally preferred.
|
||
* If not, the very presence of the link elements may need to be avoided.
|
||
*
|
||
* FUNCTIONALITY:
|
||
* Although widely used for that purpose, hyperlinks are disliked for footnote linking.
|
||
* Browsers may need to be prevented from logging these clicks in the browsing history,
|
||
* as logging compromises the usability of the 'return to previous' button in browsers.
|
||
* For that purpose, and for scroll animation, this linking is performed by JavaScript.
|
||
*
|
||
*
|
||
* @since 2.0.0 the link elements have been added and are present.
|
||
* @since 2.0.4 the link addresses were removed.
|
||
* @since 2.1.4 the presence of <a> elements was made optional, 2020-11-25T1306+0100
