\newtcbtheorem{definition}{Definition}{
  colback=red!5,
  colframe=red!70}{d}

\begin{document}

\begin{definition}{Title that has no descenders}{}
No character in the title  has a descender.
\end{definition}

\begin{definition}{Title with a descender present}{}
The title includes a character, p, with a  descender.
\end{definition}

\end{document}

生产 标题基线与框上部底部边缘之间的垂直距离不同，因为第一个标题不包含带降部的字符，而第二个标题包含这样的字符 p。我希望距离相同。据我所知，没有一个参数会tcolorbox产生该间距。我可以通过更改 的定义来\newtcbtheorem实现

\newtcbtheorem{definition}{\strut Definition}{
  colback=red!5,
  colframe=red!70}{d}

产生 到目前为止，一切都很好。（我意识到\strut增加了上方和下方的空间，但结果对我来说看起来不错。我还意识到下部文本下方的垂直空间不均匀，但出于某种原因，我发现这不那么麻烦。）

但现在假设标题延伸到第二行。那么间距又不均匀了： 我可以手动\vphantom{p}在每两行标题末尾添加一个，但一定有更好的解决方案。有什么想法吗？

（这个问题与同一问题有关，但答案涉及手动修改上部的文本。我正在寻找一种可以全局使用的解决方案，而无需修改特定框中的文本。）

Answer 1

由于问题出在标题的最后一行，您也可以使用after title app钩子在那里添加\strut。

\documentclass[12pt]{article}
\usepackage{xparse}
\usepackage[many]{tcolorbox}

\newtcbtheorem{definition}{Definition}{
  colback=red!5,
  colframe=red!70, 
  after title app=\strut}{d}

\begin{document}

\begin{definition}{Title that with no descenders}{}
No character in the title  has a descender.
\end{definition}

\begin{definition}{Title with a descender present}{}
The title includes a character, p, with a  descender.
\end{definition}

\begin{definition}{Title that with no descenders - The same box with a two-line title}{}
No character in the title  has a descender.
\end{definition}

\begin{definition}{Title with a descender present - The same box with a two-line title with a p}{}
The title includes a character, p, with a  descender.
\end{definition}

\end{document}

Answer 2

我认为你可以用以下方法解决你的问题description delimiters={\strut}{\strut}：

\documentclass[12pt]{article}
\usepackage{xparse}
\usepackage[many]{tcolorbox}

\newtcbtheorem{definition}{Definition}{
  description delimiters={\strut}{\strut},
  colback=red!5,
  colframe=red!70}{d}

\begin{document}

\begin{definition}{Title that with no descenders}{}
No character in the title  has a descender.
\end{definition}

\begin{definition}{Title with a descender present}{}
The title includes a character, p, with a  descender.
\end{definition}

\begin{definition}{Title that with no descenders - The same box with a two-line title}{}
No character in the title  has a descender.
\end{definition}

\begin{definition}{Title with a descender present - The same box with a two-line title with a p}{}
The title includes a character, p, with a  descender.
\end{definition}

\end{document}
