如何在 tcbtheorem 中换行

Question

我认为我的问题可能真的很基本，但是我查看了文档并无法弄清楚当标题太长时如何强制文本在 tcolorbox 标题内换行。

\documentclass[a4paper,11pt]{book}

\usepackage{lipsum}
\usepackage{amsmath,amssymb}
\usepackage[most]{tcolorbox}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{lmodern}

\tcbset{
    thmbox/.style={
        enhanced,
        breakable,
        sharp corners=all,
        fonttitle=\bfseries\normalsize,
        fontupper=\normalsize\itshape,
        top=0mm,
        bottom=0mm,
        right=0mm,
        colback=white,
        colframe=white,
        colbacktitle=white,
        coltitle=black,
        attach boxed title to top left,
        boxed title style={empty, size=minimal, bottom=1.5mm},
        overlay unbroken ={
            \draw (title.south west)--(title.south east);
            \draw ([xshift=3.5mm]frame.north west)|-%
                  (frame.south east)--(frame.north east);},
        overlay first={
            \draw (title.south west)--(title.south east); 
            \draw ([xshift=3.5mm]frame.north west)--  ([xshift=3.5mm]frame.south west);
            \draw (frame.north east)--(frame.south east);},
        overlay middle={
            \draw ([xshift=3.5mm]frame.north west)--([xshift=3.5mm]frame.south west);
            \draw (frame.north east)--(frame.south east);},
        overlay last={
            \draw ([xshift=3.5mm]frame.north west)|-%
                  (frame.south east)--(frame.north east);},
    },
}

Answer 1

正如 Christian 所解释的那样，tcolorbox 标题没有被包装。它应该是一些单词，而不是完整的练习。但是，如果您想将问题和答案混合到同一个颜色框中，根据您的格式，可能的解决方案可能是使用短标题（或空标题），并将问题放在 tcolorbox 的上部，而解决方案放在下部。类似
