# Tikzcd question on arrows

I have a (probably easy) question on tikzcd: I want to draw two arrows from bottom to top, intersecting each other and having a label. What I tried so far

\begin{tikzcd}

\gamma & \kappa \\
&  \\
\arrow{uur} &  \arrow{uul}
\end{tikzcd}


Which gives

But this looks not really symmetric. Where is the problem? I also tried to eally use labels on the arows but it was never really clear to see which label belongs to which arrow. Any suggestions?

An alternative is, related to How to cross over only at intersections in tikzcd:

\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[column sep = large, row sep = large]
\ar[from=2-2]\gamma & \ar[from=2-1]\kappa\\
\null & \null
\end{tikzcd}
\end{document}


Result:

EDIT: Related to your comment i added only a workaround with white space.

\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[column sep = large, row sep = large]
\ar[from=2-2]\gamma & \ar[from=2-1]\kappa\\
\textcolor{white}{\gamma} & \textcolor{white}{\kappa}
\end{tikzcd}
\end{document}


• Thanks! This still looks like the part below the crossing is larger then the part over the crossing...? Do have any solution for that? – mathstackuser Jul 12 '18 at 15:08
• And also the lower part is wider then the upper part – mathstackuser Jul 12 '18 at 15:18
• @ mathstackuser : I updatd my answer. Maybe there is an better option (and someone will help later), but first i added this workaround. Hope it helps. – Bobyandbob Jul 12 '18 at 15:23
• @mathstackuser For my opinion the 2th code of the user is very good. +1 – Sebastiano Jul 12 '18 at 19:57
• Yes, I like it too! Any ideas for the second picture? – mathstackuser Jul 13 '18 at 7:19
