|
||
* 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.
|
||
*
|
||
* Link elements also raise further concerns, so that their useless proliferation needs
|
||
* to be mitigated. By contrast, due to an insufficiency in the CSS standard, real link
|
||
* elements are required to get the link color, as opposed to named colors on the basis
|
||
* of the already supported pseudo-classes :link, :hover, :active and :visited that can
|
||
* still not be used in color names.
|
||
*
|
||
* @since 2.0.0 added the link elements with hard links
|
||
* @since 2.0.4 removed the hard links on user request
|
||
* @see <https://wordpress.org/support/topic/hyperlinked-footnotes-creating-excessive-back-history/>
|
||
* @since 2.1.4 made link elements optional for styling purposes, 2020-11-25T1306+0100
|
||
* @since 2.3.0 this variable keeps its default value if hard links are enabled 2020-12-30T2313+0100
