Without using minipage, can we resize both input and output boxes of LTXexample?

Answer 1

The key width is only responsible for the formatted text, not the source code. To change the width of the typeset source code, modify your second LTXexample (without minipage) as follows:

\begin{LTXexample}[explpreset={linewidth=0.5\linewidth},width=0.5\linewidth,pos=b]
