Ich möchte einen Rahmen in einer Box oder Miniseite wie diesem Modell zeichnen. Ein Rahmen, der oben links und unten rechts anpassbar ist. Kann mir jemand helfen? Vielen Dank, JPierre
Antwort1
Hier stapele ich einfach ein paar Regeln um ein farbiges \parbox. Die Syntax ist
\specialbox{<box-color>}{<frame-color>}{<frame-length>}{<box-width>}{<content>}
Es kann inline oder als eigener Absatz verwendet werden. Die Werte von \fboxsepund \fboxrulewerden beachtet. Da es sich um eine Box handelt, wird es nicht über mehrere Seiten verteilt.
Hier ist das MWE.
\documentclass{article}
\usepackage{xcolor,stackengine,lipsum}
\newcommand\specialbox[5]{%
\kern\fboxrule%
\stackinset{r}{}{b}{0pt}{\color{#2}\rule{\fboxrule}{#3}}{%
\stackinset{r}{}{b}{-\fboxrule}{\color{#2}\rule{#3}{\fboxrule}}{%
\stackinset{l}{-\fboxrule}{t}{0pt}{\color{#2}\rule{\fboxrule}{#3}}{%
\stackinset{l}{-\fboxrule}{t}{-\fboxrule}{\color{#2}\rule{#3}{\fboxrule}}{%
\colorbox{#1}{\parbox{\dimexpr#4-2\fboxsep-2\fboxrule}{#5}}%
}}}%
\kern\fboxrule}%
}
\begin{document}
\lipsum[1]
\fboxrule=3pt\relax%
\noindent\specialbox{yellow!95!orange}{yellow!50!orange}{40pt}{\linewidth}{\lipsum[3]}
\lipsum[2]
\fboxsep=10pt\relax\fboxrule=5pt\relax%
Testing\specialbox{cyan!10}{red}{50pt}{3in}{\lipsum[4]}inline
