mdframed 包的问题

Question

mdframed包装在内容周围形成了一个漂亮的盒子。它还具有页面之间的分页功能，如下图所示

我已经完成了在框上获取概念 5：代数恒等式的装饰，但是当框在页面上中断以将部分内容带到下一页时（如下面第二张图所示），漂亮的标题“概念 5：代数恒等式”阻挡了后面的内容。

我的问题是，我们可以通过什么方法在页眉后留出一些空间，或者直接删除下一页破损部分的页眉。请帮帮我...如果有什么不清楚的地方，请见谅。

获取所需帧的代码是

Answer 1

在 mdframe 中，如果您想控制跨页面分割框架前后剩余的空间（我上面遇到的那种麻烦），可以使用上面代码部分中的选项，，splittopskip=1cm如下 所示。splitbottomskip=1cm\mdfdefinestyle

\mdfdefinestyle{theoremstyle}{% 
outerlinewidth=1pt,
innerlinewidth=3pt,
roundcorner=5pt,
linecolor=black,
shadow=true,
splittopskip=1cm,         % THIS IS THE REQUIRED OPTION FOR SPACE ABOVE THE SPLIT ON THE SECOND PAGE
splitbottomskip=1cm,      % THIS IS THE REQUIRED OPTION FOR SPACE BELOW THE SPLIT ON THE FIRST PAGE 
tikzsetting={shading=axis,top color=gray!10},
innertopmargin=1.2\baselineskip,
skipabove={\dimexpr0.5\baselineskip+\topskip\relax},
needspace=3\baselineskip,
frametitlefont=\sffamily\bfseries,
settings={\global\stepcounter{theorem}},
}
