Supplemental Content with Docinfo
It’s possible to inject supplemental content into the output document using docinfo files. This core feature of AsciiDoc has been adapted to work with the reveal.js converter.
Currently, there are three insertion locations for docinfo content in a reveal.js document:
- head
-
content is inserted after the last child of the
<head>element - header
-
content is inserted before the first child of the
<div class="slides">element (before the slides) - footer
-
content is inserted after the last child of the
<div class="slides">element (after the slides)
The content you want to insert goes into a sibling file of the slide deck document with the following filename patterns:
- head
-
docinfo-revealjs.html - header
-
docinfo-header-revealjs.html - footer
-
docinfo-footer-revealjs.html
For example, let’s say you want to embed a tweet into your slide deck. You might inject the shared embedding JavaScript using a footer docinfo file:
<script src="https://platform.twitter.com/widgets.js"></script>You then need to set the following document attribute in the AsciiDoc header:
:docinfo: shared
When this attribute is defined, the converter will automatically read the docinfo file(s) and insert the contents into the specified location in the output document.
