我使用“阴影”来向读者表明文本是关于某些特殊内容的。这很好用，但我无法将框扩展到整页。这怎么可能呢？我使用 LYX，我可以想象这可以通过某种方式使用 renewcommand 来实现？！对此有什么提示吗？
现在它看起来是这样的：
目前“阴影”的问题是：1）宽度仅为文本的宽度 2）“阴影”区域内某些文本中包含的脚注不会显示在任何地方（编号有效）

正如您上一个问题所建议的，您可以使用mdframed。与您的样式请求相关，您应该定义一种新样式：
\mdfdefinestyle{shaded}{%
skipabove=\topskip,skipbelow=\topskip,
hidealllines=true,backgroundcolor=shadecolor,
leftmargin=\dimexpr-\oddsidemargin-1in-\hoffset\relax,
rightmargin=\dimexpr-\marginparsep-\marginparwidth-\evensidemargin\relax,
innerleftmargin=\dimexpr\oddsidemargin+1in+\hoffset\relax,
innerrightmargin=\dimexpr\marginparsep+\marginparwidth+\evensidemargin\relax,
}
通过这些设置，修改后的 mwe 如下所示：
\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage{xcolor}
\usepackage{float}
\usepackage{mdframed}
\definecolor{shadecolor}{rgb}{0.171875, 0.6640625, 0.8828125}
\usepackage[demo]{graphicx}
\mdfdefinestyle{shaded}{%
skipabove=\topskip,skipbelow=\topskip,
hidealllines=true,backgroundcolor=shadecolor,
leftmargin=\dimexpr-\oddsidemargin-1in-\hoffset\relax,
rightmargin=\dimexpr-\marginparsep-\marginparwidth-\evensidemargin\relax,
innerleftmargin=\dimexpr\oddsidemargin+1in+\hoffset\relax,
innerrightmargin=\dimexpr\marginparsep+\marginparwidth+\evensidemargin\relax,
}
