+\subsubsection*{The LON-CAPA markup language}
 
 Content documents are created in the LON-CAPA markup language. Like HTML, which is the language used to create all content on the web, the LON-CAPA language is a \emph{markup language}. A markup language is simply structured with \emph{tags}: each structure in the document starts with a \emph{start tag} like \texttt{<problem>} and ends with an \emph{end tag} like \texttt{</problem>}.
 Additionally, each structure (called an \emph{element}) can have \emph{attributes}, each one composed of a name and a value. For instance, \texttt{<foil value="true">} starts a true foil.
 A markup language is defined essentially with a list of elements and attributes, and rules specifying which element is allowed inside which other element.
-The LON-CAPA language includes most HTML elements, and adds more elements which are described in this manual. The syntax is similar to HTML, but with an additional constraint: when an element is started with a start tag, it must always be closed with an end tag.

+The LON-CAPA language includes most HTML elements, and adds more elements which are described in this manual. The syntax is similar to HTML, but with an additional constraint: when an element is started with a start tag, it must always be closed with an end tag (unless the empty element syntax is used, as with \texttt{<hr/>}).
 This syntax is sometimes called ``XML'' in this manual. XML is a specific syntax for markup languages, but the LON-CAPA language is actually not using the XML syntax, which would require escaping special characters in scripts.
+
+HTML elements are not listed in this manual, but good resources are available on the web to learn HTML. For instance:
+\begin{itemize}
+\item Learn web development:\\
+\texttt{https://developer.mozilla.org/en-US/docs/Learn/HTML}
+\item HTML element reference:\\
+\texttt{https://developer.mozilla.org/en-US/docs/Web/HTML/Reference}
