我想删除框架并为我的代码块设置浅灰色背景。
我知道我可以使用colorbox诸如\begin{tcolorbox}，但我不知道将它放在哪里。
Sphinx 使用这个环境：
\newenvironment{sphinxVerbatim}{%
% first, let's check if there is a caption
\ifx\sphinxVerbatimTitle\empty
\sphinxvspacefixafterfrenchlists
\parskip\z@skip
\vskip\sphinxverbatimsmallskipamount
% there was no caption. Check if nevertheless a label was set.
\ifx\sphinxLiteralBlockLabel\empty\else
% we require some space to be sure hyperlink target from \phantomsection
% will not be separated from upcoming verbatim by a page break
\needspace{\sphinxliteralblockwithoutcaptionneedspace}%
\phantomsection\sphinxLiteralBlockLabel
\fi
\else
\parskip\z@skip
\if t\spx@opt@literalblockcappos
\vskip\spx@abovecaptionskip
\def\sphinxVerbatim@Before
{\sphinxVerbatim@Title\nointerlineskip
\kern\dimexpr-\dp\strutbox+\sphinxbelowcaptionspace
% if no frame (code-blocks inside table cells), remove
% the "verbatimsep" whitespace from the top (better visually)
\ifspx@opt@verbatimwithframe\else-\sphinxverbatimsep\fi
% caption package adds \abovecaptionskip vspace, remove it
\spx@ifcaptionpackage{-\abovecaptionskip}{}\relax}%
\else
\vskip\sphinxverbatimsmallskipamount
\def\sphinxVerbatim@After
{\nointerlineskip\kern\dimexpr\dp\strutbox
\ifspx@opt@verbatimwithframe\else-\sphinxverbatimsep\fi
\spx@ifcaptionpackage{-\abovecaptionskip}{}\relax
\sphinxVerbatim@Title}%
\fi
\def\@captype{literalblock}%
\capstart
% \sphinxVerbatimTitle must reset color
\setbox\sphinxVerbatim@TitleBox
\hbox{\begin{minipage}{\linewidth}%
% caption package may detect wrongly if top or bottom, so we help it
\spx@ifcaptionpackage

\sphinxVerbatimTitle
\end{minipage}}%
\fi
\global\let\sphinxLiteralBlockLabel\empty

% fancyvrb's Verbatim puts each input line in (unbreakable) horizontal boxes.

% - The codeline counter will be increased only once.
% - The wrapped material will not break across pages, it is impossible
% to achieve this without extensive rewrite of fancyvrb.
% - The (not used in sphinx) obeytabs option to Verbatim is
% broken by this change (showtabs and tabspace work).

% \baselineskip, F is the framed.sty \FrameHeightAdjust macro, default 6pt.
% Formula valid for F < 10pt.
% - distance of baseline of caption to top of frame is like for tables:
% \sphinxbelowcaptionspace (=0.5\baselineskip)
% - if no caption: distance of last text baseline to code frame is S+(B-F),
% with S = \sphinxverbatimtopskip (=\smallskip)
% - and distance from bottom of frame to next text baseline is
% \baselineskip+\parskip.
% The \trivlist is used to avoid possible "too deeply nested" error.
\itemsep \z@skip
\topsep \z@skip
\partopsep \z@skip
% trivlist will set \parsep to \parskip = zero
% \leftmargin will be set to zero by trivlist
\rightmargin\z@
\parindent \z@% becomes \itemindent. Default zero, but perhaps overwritten.

看起来你应该能够通过 Sphinx 配置编辑代码块的框架和背景颜色，而不是摆弄 TeX 文件。此链接有一些关于此内容的好信息：
https://www.sphinx-doc.org/en/master/latex.html
具体来说，“verbatimwithframe”、“VerbatimColor”和“VerbatimBorderColor”元素似乎与您的问题相关。
编辑：
经过一番尝试后，添加：
# conf.py
latex_elements = {
"sphinxsetup": 'verbatimwithframe=false, VerbatimColor={gray}{0.95}',
}
latex_elements在 Sphinx 项目中的文件字段中，conf.py您可以更改逐字块的背景颜色。
