+% \section{Efficient use of Ti\textit{k}Z styles}
+% Ti\textit{k}Z are very powerful and their use is recommended also with \hftikz. For example, an intelligent way to proceed if two different highlighting colors have to be used is as follows:
+%\begin{verbatim}
+%\tikzset{offset definition/.style={
+%    above left offset={-0.1,0.6},
+%    below right offset={0.1,-0.45},
+%  },
+%  h1/.style={
+%    offset definition,
+%    set fill color=green!50!lime!60,
+%    set border color=green!40!black,
+%  },
+%  h2/.style={
+%    offset definition,
+%    set fill color=blue!20!cyan!60,
+%    set border color=blue!60!cyan,
+%  }
+%}
+%\end{verbatim}
+%\tikzset{offset definition/.style={
+%    above left offset={-0.1,0.6},
+%    below right offset={0.1,-0.45},
+%  },
+%  h1/.style={
+%    offset definition,
+%    set fill color=green!50!lime!60,
+%    set border color=green!40!black,
+%  },
+%  h2/.style={
+%    offset definition,
+%    set fill color=blue!20!cyan!60,
+%    set border color=blue!60!cyan,
+%  }
+%}
+% Their use in the document is:
+% \begin{verbatim}
+% \[\tikzmarkin[h1]{st-a}x + \dfrac{y}{z} = 400\tikzmarkend{st-a}\]
+% \[\tikzmarkin[h2]{st-b}x + \dfrac{y}{z} = 400\tikzmarkend{st-b}\]
+% \end{verbatim}
+% which gives as result:
+% \[\tikzmarkin[h1]{st-a}x + \dfrac{y}{z} = 400\tikzmarkend{st-a}\]
+% and
+% \[\tikzmarkin[h2]{st-b}x + \dfrac{y}{z} = 400\tikzmarkend{st-b}\]
