Espaçamento horizontal e vertical em ambiente 'shaded*' usando o pacote 'framed.sty'

Question

Usando o framed.stypacote para desenhar caixas sombreadas ao redor do texto com o shaded*ambiente, há apenas um parâmetro para definir o espaçamento ao redor do texto. \FrameSepajusta simultaneamente o espaçamento horizontal e vertical do texto a partir dos limites da caixa sombreada. Sendo estranho, colocar \FrameSep=1emfornece as margens esquerda/direita desejadas, enquanto \FrameSep=0.75emfornece o espaçamento superior/inferior desejado.

Existe uma maneira de cavar dentro framed.stypara definir o espaçamento esquerdo/direito e superior/inferior de forma independente?

Se (como suspeito) a coisa a fazer é mudar para algo muito mais flexível mdframed.sty, como produzir um shaded*ambiente simples com isso? - Confesso que estou achando a documentação difícil de decifrar.

Answer 1

Aqui está um exemplo simples:

\documentclass{article}
\usepackage{xcolor}
\usepackage{mdframed}
\begin{document}

\noindent Normal text here ...  
\begin{mdframed}[leftmargin=1cm,
    skipabove=1cm,    
    linecolor=blue,
    backgroundcolor=red!10,
    linewidth=2pt,
    innerleftmargin=1em,
    innerrightmargin=1em,
    innertopmargin=.75em,
    innerbottommargin=.75em,
]
If (as I suspect) the thing to do is to move to the much more flexible  mdframed.sty, how does one produce a simple shaded* environment with that? -- I confess I'm finding the documentation hard to crack.
\end{mdframed}

\end{document}

Não acho que a documentação seja difícil, veja por exemplo a página 6, onde você pode encontrar a maioria das configurações para comprimentos ajustáveis ​​de mdframed:

Answer 2

Aqui está uma solução com framed: Redefini o shaded*ambiente para incorporar valores para \leftskipe rightskip. Observe que requer uma linha em branco antes do texto a seguir.

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{ebgaramond}
\usepackage[showframe]{geometry}
\usepackage[svgnames]{xcolor}
\usepackage{lettrine}
\usepackage{framed}
\renewenvironment{shaded*}{%
\def\FrameCommand{\fboxsep=\FrameSep\colorbox{shadecolor}}%
\MakeFramed{\advance\hsize-\width\FrameRestore}%
\leftskip 1.5em \rightskip 1.5em}%
{\endMakeFramed}%
\colorlet{shadecolor}{Gainsboro!60!MistyRose}

\begin{document}

\lettrine{H}{owever}, the egg only got larger and larger, and more and more human:
when she had come within a few yards of it, she saw that it had eyes
and a nose and mouth; and when she had come close to it, she saw clearly
that it was HUMPTY DUMPTY himself. ‘It can’t be anybody else!’ she said
to herself. ‘I’m as certain of it, as if his name were written all over
his face.’
\begin{shaded*}
  \lettrine{I}{t} might have been written a hundred times, easily, on that enormous
  face. Humpty Dumpty was sitting with his legs crossed, like a Turk, on
  the top of a high wall--such a narrow one that Alice quite wondered how
  he could keep his balance--and, as his eyes were steadily fixed in the
  opposite direction, and he didn’t take the least notice of her, she
  thought he must be a stuffed figure after all.

  ‘And how exactly like an egg he is!’ she said aloud, standing with her
  hands ready to catch him, for she was every moment expecting him to
  fall.

  ‘It’s VERY provoking,’ Humpty Dumpty said after a long silence, looking
  away from Alice as he spoke, ‘to be called an egg--VERY!’

  ‘I said you LOOKED like an egg, Sir,’ Alice gently explained. ‘And some
  eggs are very pretty, you know’ she added, hoping to turn her remark
  into a sort of a compliment.
\end{shaded*}

‘Some people,’ said Humpty Dumpty, looking away from her as usual, ‘have
no more sense than a baby!’
