更改校样环境的顶部边距

Question

我认为proof环境的顶部边距太大。我希望它在视觉上更接近它所指的命题或定理。

我已经验证过，在环境\vspace{-3ex}前添加proof可以得到我想要的结果。现在，我该如何修改证明环境？

我试图重新定义它，但我不知道原始定义，而且在我的 Latex 发行版中也没有找到它。

梅威瑟：

\documentclass{article}

\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{thmtools}
\usepackage[dvipsnames]{xcolor}

\declaretheoremstyle[
    spaceabove=\topsep,
    spacebelow=\topsep,
    name={\color{Blue}Proposition},
]{propsty}
\declaretheorem[style=propsty]{prop}

\begin{document}
\begin{prop}
    This is a proposition.
\end{prop}

\begin{proof}
    The proof is left as an exercise for the reader.
\end{proof}

\begin{prop}
    This is another proposition.
\end{prop}

\vspace{-3ex}
\begin{proof}
    The proof is left as an exercise for the reader and it's closer to the
    relevant proposition.
\end{proof}
\end{document}

选择负值似乎spacebelow没有任何作用。所以我决定改变证明环境。

例如，你可以这样做：

\documentclass{article}

\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{thmtools}
\usepackage[dvipsnames]{xcolor}

\declaretheoremstyle[
    spaceabove=0\topsep,
    spacebelow=0\topsep,
    name={\color{Blue}Proposition},
]{propsty}
\declaretheorem[style=propsty]{prop}

\declaretheoremstyle[
    spaceabove=0.5\topsep,
    spacebelow=0.5\topsep,
    name={\color{Blue}Proposition},
]{propsty}
\declaretheoremstyle[
    spaceabove=0.5\topsep,
    spacebelow=1\topsep,
    name=Proof,
    headfont=\itshape, numbered=no
]{proofsty}
\declaretheorem[style=proofsty]{myproof}
\raggedbottom
\begin{document}
\begin{prop}
    This is a proposition.
\end{prop}

\begin{myproof}
    The proof is left as an exercise for the reader.
\end{myproof}

\begin{prop}
    This is another proposition.
\end{prop}


\begin{myproof}
    The proof is left as an exercise for the reader and it's closer to the
    relevant proposition.
\end{myproof}
\end{document}
