I would like to create frames / boxes for equations or text like in the Beamer class: 
outisde of the beamer documentclass, for example in the article class. Is there any package or trick to do this?
thanks

3Take a look at the mdframed package. Does that look like what you want?– Andrew StaceySep 10, 2013 at 11:22

tcolorbox has also a beamer skin:
\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{skins}
\colorlet{xlightblue}{blue!5}
\newtcolorbox{beamerlikethm}[1]{
title=#1,
beamer,
colback=xlightblue,
colframe=blue!30,
fonttitle=\bfseries,
left=1mm,
right=1mm,
top=1mm,
bottom=1mm,
middle=1mm
}
\begin{document}
\begin{beamerlikethm}{Theorem (Pythagoras)}
\[ a^2 + b^2 = c^2 \]
\end{beamerlikethm}
\end{document}
As Gonzalo suggested, could happen that your box necessitate of being split on different pages. The library breakable of the package deal with this problem.
An example:
\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{breakable,skins}
\usepackage{lipsum}
\colorlet{xlightblue}{blue!5}
\newtcolorbox{beamerlikethm}[1]{
title=#1,
beamer,
colback=xlightblue,
colframe=blue!30,
fonttitle=\bfseries,
left=1mm,
right=1mm,
top=1mm,
bottom=1mm,
middle=1mm,
breakable,
}
\begin{document}
\begin{beamerlikethm}{Theorem (Pythagoras)}
\[ a^2 + b^2 = c^2 \]
\end{beamerlikethm}
\lipsum[1-4]
\begin{beamerlikethm}{Something}
\lipsum[5]
\end{beamerlikethm}
\end{document}

Perhaps you might want to add the
breakableoption so the box admits page breaks. Sep 10, 2013 at 12:43 -
@GonzaloMedina: that's absolutely right. I'll add a reference on this. Sep 10, 2013 at 12:56

Just some hints for adjusting the vertical spacing of the formula in the example: the additional loading of the
amsmathpackage corrects the spacing before the equation. Alternatively, thetcolorboxlibrarytheoremscould be used (which loadsamsmath). For multiline formulas, the library has special support for the spacing at the begin of the box, e.g. see the option 'ams nodisplayskip'. :-) Sep 11, 2013 at 6:45 -
@ThomasF.Sturm: thank you very much for the suggestion. I will modify the answer accordingly. :) Sep 11, 2013 at 7:00
Another approach with the »tcolorbox« package and its theorems library.
\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage[most]{tcolorbox}
\newtcbtheorem{corollary}{Corollary}{%
breakable,
colback=blue!10,
colframe=blue!25,
fonttitle=\bfseries
}{cor}
\begin{document}
\begin{corollary}{Title}{dummy}
\[
x+y=y+x
\]
\end{corollary}
\end{document}

@GonzaloMedina: You forgot to mention that the
breakableoption needs thebreakablelibrary. Since it was not asked here for boxes which allow page breaks, there was no necessity to add it. But as you mention that now, the OP is aware of it. Sep 10, 2013 at 12:53 -
1Right, I didn't mention the library since I always load
tcolorboxusing\usepackage[most]{tcolorbox}, so I don't have to worry about loading the libraries explicitly. Sep 10, 2013 at 12:57 -
tcolorbox package might be helpful.
\documentclass{article}
\usepackage{tcolorbox}
\begin{document}
\begin{tcolorbox}[colback=blue!5,colframe=blue!40!black,title=Theorem (Pythagoras)]
\[ a^2 + b^2 = c^2 \]
\end{tcolorbox}
\end{document}
The similar question was asked here.
