I would like to remove the frames and set a light grey shade background to my code blocks.
I know I could use colorbox such as \begin{tcolorbox}, but I have no idea where to place it.
Sphinx uses this environment:
\newenvironment{sphinxVerbatim}{% % first, let's check if there is a caption \ifx\sphinxVerbatimTitle\empty \sphinxvspacefixafterfrenchlists \parskip\z@skip \vskip\sphinxverbatimsmallskipamount % there was no caption.
