Text between two lines

Question

i'd like to write words that fit between two lines.

i found the following code:

\documentclass[parskip,paper=a4]{scrartcl}
\usepackage{calc}

\setlength{\parindent}{0pt}
\setlength{\fboxsep}{0pt}
\pagestyle{empty}

\newsavebox{\mybox}
\newenvironment{mb}
{\begin{lrbox}{\mybox}\begin{minipage}[4mm]{\columnwidth-2\fboxsep}}%
{\end{minipage}\end{lrbox}\par\vspace{10mm}\noindent\fbox{\usebox{\mybox}}\par}

\begin{document}
\begin{mb}
\Huge Stackexchange
\end{mb}
\end{document}

what i like to get is something like this:

edit: to be more clear ... sorry!

i'd like the lines to be the full width of the page with only some characters in front of the two lines.

Answer 1

The following example puts the text in a box, then it reduces the height and depth to put a frame (\fbox) without margin around the shrinked box. The original height and depth is kept by \vphantom.

\documentclass[parskip,paper=a4]{scrartcl}

\newcommand*{\TwoLinesBox}[1]{%
  \leavevmode
  \begingroup
    \sbox0{\,#1\,}%
    \vphantom{\copy0}% keep original height and depth
    \sbox2{x}% new height
    \ht0=\ht2 %
    \dp0=0pt %
    \setlength{\fboxsep}{0pt}% \fbox without additional inner margins
    \fbox{\copy0}%
  \endgroup
}

\begin{document}
\Huge
\noindent
\TwoLinesBox{Stackexchange}
\end{document}

Half open box, spanning the line

The following example uses a tabular environment with one column that spans the whole line width. The two lines are set at the beginning of the row.

The code uses plain TeX macros and primitives. Literature:

• Donald E. Knuth: The TeXbook
• Victor Eijkhout: TeX by Topic

The example file:

\documentclass{article}

\usepackage{array}

\newenvironment{twolines}{%
  \par
  \noindent
  \begin{tabular}{@{}>{\AddTwoLines}p{\linewidth}@{}}%
}{%
  \end{tabular}%
}

\newcommand*{\AddTwoLines}{%
  \noindent
  \sbox0{\vrule\vphantom{x}}%
  \rlap{%
    \vbox{\hrule width\linewidth}%
  }%
  \rlap{%
    \raise\ht0\vbox{\hrule width\linewidth}%
  }%
  \copy0 %
  \,\ignorespaces
}

\begin{document}
\Huge
\begin{twolines}
  Stack\\
  Exchange
\end{twolines}
\end{document}
