高度为 0 的 vbox 仍然添加边距

Question

我想将这个框放在描述列表旁边。它应该不是影响列表本身。我使用 mbox，并且 mbox 内有一个高度为 0 的 vbox。但是，它仍然会将文本向下推。我该如何防止这种情况？

\documentclass{article}
\usepackage{enumitem}
\begin{document}

\begin{description}[style=multiline,leftmargin=3cm]
  \item[Item 1]
  \mbox{%
    \vbox to 0cm{\hbox to 10cm{\hfill \fbox{OK}}}
   }
   \begin{minipage}{8cm}
  Here is information. This is a multiline description. We will copy
  these lines a few times. Here is information. This is a multiline description.
  We will copy these lines a few times. Here is information. This is a multiline
  description. We will copy these lines a few times. Here is information.
  \end{minipage}

  \item[Item 2]
  \mbox{%
    \vbox to 0cm{\hbox to 10cm{\hfill \fbox{Fail}}}
   }
   \begin{minipage}{8cm}
  Here is information. This is a multiline description. We will copy
  these lines a few times. Here is information. This is a multiline description.
  We will copy these lines a few times. Here is information. This is a multiline
  description. We will copy these lines a few times. Here is information. This is
  a multiline description. 
  \end{minipage}

  \item[Another item here]
  \mbox{%
    \vbox to 0cm{\hbox to 10cm{\hfill \fbox{OK}}}
   }
   \begin{minipage}{8cm}
  Here is information. This is a multiline description. We will copy
  these lines a few times. Here is information. This is a multiline description.
  We will copy these lines a few times. Here is information. This is a multiline
  description. We will copy these lines a few times. Here is information. This is
  a multiline description. We will copy these lines a few times.Here is
  information. This is a multiline description. We will copy these lines a few
  time.
  \end{minipage}

\end{description}

\end{document}

我希望第一行与描述标签出现在同一行：

知道应该改变什么吗？

Answer 1

排版\vbox高度为零，但它位于小页面之上，并且其参考点位于基线。

您可以在以下内容中添加信息minipage：

\documentclass{article}
\usepackage{enumitem}

\newcommand{\OF}[1]{%
  \makebox[0pt][l]{\hspace{10cm}\fbox{#1}}%
  \ignorespaces
}

\begin{document}

\begin{description}[style=multiline,leftmargin=3cm]
\item[Item 1]
  \begin{minipage}[t]{8cm}\OF{OK}
  Here is information. This is a multiline description. We will copy
  these lines a few times. Here is information. This is a multiline description.
  We will copy these lines a few times. Here is information. This is a multiline
  description. We will copy these lines a few times. Here is information.
  \end{minipage}

  \item[Item 2]
  \begin{minipage}[t]{8cm}\OF{FAIL}
  Here is information. This is a multiline description. We will copy
  these lines a few times. Here is information. This is a multiline description.
  We will copy these lines a few times. Here is information. This is a multiline
  description. We will copy these lines a few times. Here is information. This is
  a multiline description. 
  \end{minipage}

  \item[Another item here]
  \begin{minipage}[t]{8cm}\OF{OK}
  Here is information. This is a multiline description. We will copy
  these lines a few times. Here is information. This is a multiline description.
  We will copy these lines a few times. Here is information. This is a multiline
  description. We will copy these lines a few times. Here is information. This is
  a multiline description. We will copy these lines a few times.Here is
  information. This is a multiline description. We will copy these lines a few
  time.
  \end{minipage}

\end{description}

\end{document}

如果你想使用更大的标签，你可以使用

\newcommand{\OF}[1]{%
  \makebox[0pt][l]{%
    \hspace{10cm}%
    \raisebox{\dimexpr\fontcharht\font`T+\fboxsep+\fboxrule-\height}[0pt][0pt]{%
      \fbox{\vphantom{A}#1}%
    }%
  }%
  \ignorespaces
}

\OF{\Huge OK}标签将会随之向下移动。
