In this post I've found the following amazing code to highlight text on several lines.
The problem is that code dosen't work well with formulas : for example, fraction using the mode display
are partially out of the highlighting frame.
Here is the code with one content showing the problem.
\documentclass{article}
\usepackage{soul}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{amsmath}
\usepackage{xcolor}
\makeatletter
\newcommand{\defhighlighter}[3][]{%
\tikzset{every highlighter/.style={color=#2, fill opacity=#3, #1}}%
}
\defhighlighter{yellow}{.5}
\newcommand{\highlight@DoHighlight}{
\fill[
outer sep = -15pt, inner sep = 0pt,
every highlighter, this highlighter
](
$(begin highlight)+(0,8pt)$) rectangle ($(end highlight)+(0,-3pt)$
);
}
\newcommand{\highlight@BeginHighlight}{
\coordinate (begin highlight) at (0,0) ;
}
\newcommand{\highlight@EndHighlight}{
\coordinate (end highlight) at (0,0) ;
}
\newdimen\highlight@previous
\newdimen\highlight@current
\DeclareRobustCommand*\highlight[1][]{%
\tikzset{this highlighter/.style={#1}}%
\SOUL@setup
%
\def\SOUL@preamble{%
\begin{tikzpicture}[overlay, remember picture]
\highlight@BeginHighlight
\highlight@EndHighlight
\end{tikzpicture}%
}%
%
\def\SOUL@postamble{%
\begin{tikzpicture}[overlay, remember picture]
\highlight@EndHighlight
\highlight@DoHighlight
\end{tikzpicture}%
}%
%
\def\SOUL@everyhyphen{%
\discretionary{%
\SOUL@setkern\SOUL@hyphkern
\SOUL@sethyphenchar
\tikz[overlay, remember picture] \highlight@EndHighlight ;%
}{}{%
\SOUL@setkern\SOUL@charkern
}%
}%
%
\def\SOUL@everyexhyphen##1{%
\SOUL@setkern\SOUL@hyphkern
\hbox{##1}%
\discretionary{%

\SOUL@setkern\SOUL@charkern

}%
%
\def\SOUL@everysyllable{%
\begin{tikzpicture}[overlay, remember picture]
\path let \p0 = (begin highlight), \p1 = (0,0) in \pgfextra
\global\highlight@previous=\y0
\global\highlight@current =\y1
\endpgfextra (0,0) ;
\ifdim\highlight@current < \highlight@previous
\highlight@DoHighlight
\highlight@BeginHighlight
\fi
\end{tikzpicture}%
\the\SOUL@syllable
\tikz[overlay, remember picture] \highlight@EndHighlight ;%
}%
\SOUL@

\makeatother

I suppose I could write some more text here.

Is someone could help me to fix it?
minimal
for minimal working examples! It is not designed for that even if the name suggest it, has no real benefits and frequently causes issues!\usepackage{xcolor}
. Also, if you use\usepackage{amsmath}
you can use\dfrac{}{}
instead of\displaystyle \frac{}{}
.\soulomit
around the formula. That would at least prevent the highlighting from striking through it.
