Горизонтальный и вертикальный интервал в затененной* среде с использованием пакета framed.sty

Question

Используя framed.styпакет для рисования затененных рамок вокруг текста с shaded*окружающей средой, есть только один параметр для установки интервала вокруг текста. \FrameSepодновременно регулирует как горизонтальный, так и вертикальный интервал текста от границ затененного блока. Будучи неудобным, размещение \FrameSep=1emдает левые/правые поля, которые я хочу, в то время как \FrameSep=0.75emдает верхний/нижний интервал, который я хочу.

Есть ли способ покопаться внутри, framed.styчтобы независимо установить отступы слева/справа и сверху/снизу?

Если (как я подозреваю) нужно перейти на гораздо более гибкий mdframed.sty, как можно создать с его помощью простую shaded*среду? -- Признаюсь, мне сложно разобраться в документации.

Answer 1

Вот простой пример:

\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}

Я не думаю, что документация сложная, см., например, страницу 6, где вы можете найти большинство настроек для регулируемой длины mdframed:

Answer 2

Вот решение с framed: Я ​​переопределил shaded*среду, чтобы включить значения для \leftskipи rightskip. Обратите внимание, что перед следующим текстом требуется пустая строка.

\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!’
