[Tex/LaTex] beamer style text box

Question

If you're using beamer you can do some nice text boxes using:

\begin{block}{block title}content of block\end{block}

Which gives a text box something like this (the box with the header Esimerkki):

How can I do the same thing in a regular latex document (I really like the look of the beamer text boxes and would like as close to this as possible).

Minimal reproducible example:

\documentclass{scrartcl}
\begin{document}
I wish I were inside of a really super cool text box so all the word would stop and look at me and say wow that text is pretty.  But alas I am just ordinary \LaTeX{} text.  I am sad.
\end{document} 

Answer 1

Try the tcolorbox package. A little example

\documentclass{article}
\usepackage{tcolorbox}
\usepackage{lipsum}

\begin{document}

\begin{tcolorbox}[colback=green!5,colframe=green!40!black,title=A nice heading]
\lipsum[2]
\end{tcolorbox}

\end{document}

The mdframed package can also be an option:

\documentclass{article}
\usepackage{xcolor}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}

\mdfdefinestyle{mystyle}{%
linecolor=green!40!black,outerlinewidth=1pt,%
frametitlerule=true,frametitlefont=\sffamily\bfseries\color{white},%
frametitlerulewidth=1pt,frametitlerulecolor=green!40!black,%
frametitlebackgroundcolor=green!40!black,
backgroundcolor=green!5,
innertopmargin=\topskip,
roundcorner=5pt
}
\newmdenv[style=mystyle]{exa}
\newenvironment{example}[1]
  {\begin{exa}[frametitle=#1]}
  {\end{exa}}

\begin{document}

\begin{example}{The Title}
\lipsum[1]
\end{example}

\end{document}
