框的边缘写着“标题”，周围留有空白

Question

给定一个framed包装盒（或您选择的任何其他包装盒），我怎样才能使第一行（只有一两个单词）浮动在盒子的边框上，并在左右两侧留出一些空白？

我正在寻找以下效果：

Answer 1

你可以使用tikz库来尝试一下。我猜你想要一个全衬里的盒子，但不确定？

\documentclass[12pt]{article}
\usepackage{tikz}
\usetikzlibrary{backgrounds}
\begin{document}

\tikzstyle{background rectangle}=[thin,draw=black]
\begin{tikzpicture}[show background rectangle]

\node[align=justify, text width=\textwidth, inner sep=1em]{
Some sample text here thats in the box
};

\node[xshift=3ex, yshift=-0.7ex, overlay, fill=white, draw=white, above 
right] at (current bounding box.north west) {
\textit{Push}
};

\end{tikzpicture} 
\end{document}

Answer 2

tcolorbox这是用于绘制框并将标题放在边缘的版本。

这是源代码：

\documentclass{article}

\usepackage[skins]{tcolorbox}

\newtcolorbox{myframe}[2][]{%
  enhanced,colback=white,colframe=black,coltitle=black,
  sharp corners,boxrule=0.4pt,
  fonttitle=\itshape,
  attach boxed title to top left={yshift=-0.3\baselineskip-0.4pt,xshift=2mm},
  boxed title style={tile,size=minimal,left=0.5mm,right=0.5mm,
    colback=white,before upper=\strut},
  title=#2,#1
}

\begin{document}

\begin{myframe}{Push}
  Some sample text here thats in the box.
\end{myframe}

\begin{myframe}{Pop}
  Some sample text. Some sample text. Some sample text. Some sample text.
  Some sample text. Some sample text. Some sample text. Some sample text.
  Some sample text. Some sample text. Some sample text. Some sample text.
\end{myframe}

\end{document}
