[[HTML]], the predominant [[markup language]] for web pages, has no mechanism for adding notes. Despite a number of different proposals over the years, the [[working group]] has been unable to reach a consensus on it.<ref>{{Cite web |title=[whatwg] Footnotes, end notes, side notes |url=https://lists.whatwg.org/pipermail/whatwg-whatwg.org/2008-April/014485.html |access-date=2024-09-03 |website=lists.whatwg.org}}</ref> Because of this, [[MediaWiki]], for example, has had to introduce its own <code><nowiki><ref></ref></nowiki></code> tag for citing references in notes.

It might be argued that the [[hyperlink]] partially eliminates the need for notes, being the web's way to refer to another document. However, it does not allow citing to offline sources and if the destination of the link changes, the link can become dead or irrelevant.<ref>[[Jill Lepore]].

As of 2024, the HTML Living Standard has provided several workarounds for the inclusion of footnotes depending on length or type of annotation.<ref>{{Cite web |title=4.14 Common idioms without dedicated elements |url=https://html.spec.whatwg.org/multipage/semantics-other.html#footnotes |access-date=2024-09-03 |website=html.spec.whatwg.org}}</ref>

In instances where a user needs to add an endnote or footnote using HTML, they can add the superscript number using <code><nowiki><sup></sup></nowiki></code>, then link the superscripted text to the reference section using an [[anchor tag]]. Create an anchor tag by using <code><a name="ref1"></a></code> and then link the superscripted text to "ref1".
