is there a way to customize the \Rightarrow and \Leftrightarrow to match with my customized rightarrow?
As you can see the rightarrow between A and B is perfect. But the other two arrows are not.
\documentclass[a4paper,11pt]{book} \usepackage{tikz} \usetikzlibrary{positioning,arrows.meta} \usepackage[version=4]{mhchem} \ExplSyntaxOn \cs_set:Npn \__mhchem_arrow_options_minLength:n { {1.1em} } \ExplSyntaxOff \mhchemoptions{arrows=pgf{Straight Barb[round, angle=60:1.5pt 3]}{0.1ex}} \begin{document} I have these: \colorbox{green}{ \ce{A -> B} \qquad C $\Rightarrow$ D \qquad E $\Leftrightarrow$ F} My MWE: \colorbox{green}{G \raisebox {0.35ex} {\tikz{\draw [double equal sign distance, -{Straight Barb[round, angle=60:1.5pt 1]}] (0,0) --++ (0.3,0)}} H} \end{document}
Thank you in advance.
