Hello,
Following on from my previous questions for writing my book (thanks again Wolfgang), I have to create a solution environment like the attached image.
My problem is adjusting the length of the frame.
Thank you.
Fabrice

\setupbodyfont[newcomputermodern-book,11pt]

\defineframed
    [ACFRAME]
    [frame=off,
     width=fit,
     align=flushleft,
     location=low,
     background=color,
     backgroundcolor=lightgray,
     foregroundcolor=,
     foregroundstyle=]

\startuseMPgraphic{acframe}
    fill OverlayBox
        leftenlarged (BackSpace + 5mm)
        rightenlarged ExHeight
        withcolor "lightgray";
    setbounds currentpicture to OverlayBox;
\stopuseMPgraphic

\defineoverlay
  [acframe]
  [\useMPgraphic{acframe}]

\defineframed
   [ACFRAME]
   [...,
    background=acframe,
    ...]

Wolfgang
