# ComboStrap - Footnotes (Reference)

A footnote 1) is a syntax component that permits to add reference that will be added at the foot of the page.

Footnotes are used most commonly to provide:

• references (bibliographic citations) to reliable sources,
• explanatory information or
• source information for tables and other elements.

Without cluttering the body of the document, footnotes allow you to add:

• notes,
• citations
• and references.

When you create a footnote, a superscript number with a link appears where you added the footnote reference. Readers can click the link to jump to the content of the footnote at the bottom of the page.

## Syntax

• A footnote 2) is delimited with two parenthesis.
(( your footnote content goes here and you can add a [[https://example.com/ref|reference link]] ))

• You can also use cite for citation
((<cite></cite>))


## Demo

• The result:

The formatting in the demo is broken because it runs in a iframe but it should not be in your installation. The proof is that we have added a footnote in this page and the formatting is correct.
