Single/Double side environment with different backgrounds

Question

I'm having trouble aligning some of the elements.

1. I would like align Check Box and Cross Box to be same size so that they look nicer below is what i got so far.

2. Also it would be great if they can change in size with respect to environment with (some ratio 60% of text or so)

3. Have background so that it would be easer to read.(as shown in the second part of the question)

Thank you for your help in advance!

\newsavebox\IBox
\newenvironment{good}[2][1]
{\def\scale{#1}\begin{lrbox}{\IBox}\begin{minipage}{\dimexpr#2\linewidth-2\fboxsep-2\fboxrule\relax}\ignorespaces}
{%
    \end{minipage}\end{lrbox}%              
    \rput( \dimexpr-10\wd\IBox+\fboxsep+\fboxrule\relax,0){%               
  \scalebox{\scale}[1]{   \makebox(0,0){\put(20,0){%
 \resizebox{0.4\textwidth}{!}{\color{green!25}\Checkedbox}}}}%
        }%
    {\usebox\IBox}%
  }

        }%
    {\usebox\IBox}%
  }

\usepackage{lipsum}

\begin{document}
\lipsum[1]

\vspace{3mm}

\begin{good}{0.49}
\lipsum[1]
\end{good}\hfill
\begin{bad}{0.49}
\lipsum[1]
\end{bad}

\vspace{3mm}

\lipsum[1]
\end{document}

[UPDATE] This is a more or less second part of the answer

I would be happy if some one can put Checked-box as the background for this one.

And again there is some aligning problems with minipage but i will ignore this one for now.

Answer 1

I guess your are compiling with xelatex or latex->ps->pdf, because you are loading pst-node. If you are using pdflatex there is a strange interaction between pst-node and the option opacity of TikZ.

However you can add material to the background of your environment by the options singleextra.

frametitle={Example\hfill\resizebox{12pt}{!}{\color{red}\Crossedbox}}, 
frametitlebackgroundcolor=red!25,

singleextra={%
   \path let \p1=(P) in node[opacity=.2,red,scale=10] at (.5*\x1,.5*\y1) {\Crossedbox};
