环绕图定位

我想做一个多解决方案环境， 像那样：

在此处输入图片描述

我使用这个代码来实现奇特的开始和结束：

\documentclass{article}

\usepackage{environ}

\usepackage{wrapfig}

\usepackage{tikz}
\usetikzlibrary{fadings}
\usepackage{rotating}

\NewEnviron{solution}[1]
{
    \begin{wrapfigure}{l}{0.5\textwidth}    
        \begin{tikzpicture}
        \def\mytext{\textbf{begin #1 solution}}
        \tikzset{mynode/.style={anchor=south,inner sep=0}}
        \node[mynode]{\mytext};
        \node[scope fading=south,opacity=0.4,yscale=-1,mynode]{\mytext};
        \end{tikzpicture}
    \end{wrapfigure}

    \BODY   

    \begin{wrapfigure}{r}{0.5\textwidth}    

        \begin{turn}{180}
            \begin{tikzpicture}
            \def\mytext{\textbf{end #1 solution}}
            \tikzset{mynode/.style={anchor=south,inner sep=0}}
            \node[mynode]{\mytext};
            \node[scope fading=south,opacity=0.4,yscale=-1,mynode]{\mytext};
            \end{tikzpicture}
        \end{turn}

    \end{wrapfigure}
}

但我有这个问题：

在此处输入图片描述

我做错了什么？

答案1

更新后的版本：

我明白你想让“End # solution”在段落中浮动多行。我对 TeX 的魔力还不够熟练，无法在段落中获得两个浮动和让一个位于左上角，另一个位于右下角。我建议创建一个新问题，专门用于在一个段落内放置两个浮动元素（一个位于开头，一个位于结尾）。

我使用/定义了一个命令借用这个答案用于水平线。我对其进行了修改，删除了颜色参数。

镜像文本 I借用这个答案。答案中还有关于如何修改反射的更多详细信息。

使用 yshift 更新版本图片

原始版本：

tikz正如评论中提到的那样，您不需要为此使用。您实际上只需要 的rotating包End # solution。我没有制作出您图片中完全相同的东西，因为解决方案 1 和解决方案 2 之间不一致……希望我的假设能够解决您正在寻找的问题：

我使用xparse只是为了方便\NewDocumentEnvironment，以防您稍后决定更改参数的数量或可选性。另外，我相信不用 也可以做到这一点wrapfig。但为了得到你想要的（占据Begin # solution段落的两个行高），它似乎wrapfig效果很好。

输出如下：
