mdframed：当分割后的第一个对象是另一个 mdframed 框时，splittopskip 不起作用

问题

我想在mdframed分割（分页符）后的环境中添加空间，并且分割（分页符）后的第一个对象是另一个mdframed环境。可以吗？

答案1

这为该问题提供了半自动和全自动解决方案... 在所有情况下，它都是“自动”的，因为mdframe创建颜色填充所需的所有参数都直接从环境中获取，无需用户干预。如果用户选择“半自动”解决方案形式，它允许他们手动调用宏\padframe[padheight]以在需要的时间和地点包含填充。

在全自动解决方案中，环境Mdframed会为每个嵌套框架粘贴填充，无论框架是否拆分（但不包括外框）。在半自动和全自动版本中，默认填充高度是外框splittopskip的高度。

它从外部环境自动抓取的参数mdframe有backgroundcolor、userdefinedwidth、innerleftmargin、innerrightmargin和splittopskip（默认的 padheight）；从内部mdframe环境抓取innertopmargin、userdefinedwidth、innerleftmargin、 和innerrightmargin。

它使用这些参数来构建一组\rules，使外部的颜色呈现“填充”的外观mdframe。

修订说明：

V1：初步答案

V2：通过使用长度，消除了在\padvslop嵌套/填充时出现的水平重影线mdframe中间页面。添加 vslop 后，我必须修改构建顶部规则的方式\laps。此外，将splittopskip外框设为默认 pad 高度，而不是splitbottomskip外框。

mdframeV3：构建垫圈时，考虑了外部左右边缘不对称的问题。

\padframeV4：从外部调用 无关紧要mdframe（它们被忽略）。这意味着剩下要做的就是尝试让 总是在进入时mdframed调用\padframe。到目前为止，我的努力还没有成功。

V5：引入了Mdframed自动插入填充。我通过将参数设置\mdfManualPaddding为{T}或 ，将 MWE 设置为“手动插入填充”或“自动插入填充” {F}。使用自动填充时，将忽略手动调用\padframe。

mdframe例如，当内部定义为

splitbottomskip = 10mm, 
splittopskip = 10mm, 
roundcorner = 5pt, 
innerleftmargin = 1.1cm, 
align = center]

\padframe[1cm] % SPECIFY PAD HEIGHT EXPLICITLY
\mytext

其中 padframe 高度指定为 1cm，innerleft/rightmargins 和innertopmargin都设置为 1.1cm，结果如下：
