As you can see, this happens for all source document types that end up
rendering as HTML, not just source documents in the HTML
<tt>fossil-doc</tt> format described at the end of the prior section.


<h3>2. $NONCE</h3>

If you put the string <tt>nonce="$NONCE"</tt> or <tt>nonce='$NONCE'</tt>
anywhere in your document, the server's per-page CSP nonce value is
substituted into the document at that point. This is most useful in
combination with the HTML embedded doc type when using
<tt>&lt;script&gt;</tt> and <tt>&lt;style&gt;</tt> tags to allow that
tag to be accepted by Fossil's default
[https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP | CSP settings].


<h3>3. TH1 Documents</h3>
<h3>2. TH1 Documents</h3>

Fossil will substitute the value of [./th1.md | TH1 expressions] within
<tt>{</tt> curly braces <tt>}</tt> into the output HTML if you have
configured it with the <tt>--with-th1-docs</tt> option, which is
disabled by default.
