将页面拆分为两个相互独立的内容

Question

我想比较两门考试，因此我尝试将页面分成两个相互独立的内容，以显示 2014 年考试与 2015 年考试之间的差异。为此，我编写了以下代码，但我可以做得更进一步，如能得到任何帮助我将不胜感激。

\tcbset{
    lemmastyle/.style={enhanced, colback=white, colframe=blue!20, arc=0pt, 
                       fonttitle=\bfseries, description color=Maroon,  
                       colbacktitle=white, coltitle=DarkOliveGreen,    
                       top=\tcboxedtitleheight,
                       boxed title style={arc=0pt},
                       attach boxed title to top left={yshift=-\tcboxedtitleheight/3, 
                                                                                                            xshift=-2mm}%
                      },
}

该请求看上去适合tcbraster-的功能tcolorbox。

请查看tcolorbox文档以了解更多配置选项。
