正文顶部和底部的间距均匀

tag-icon • tag-icon vertical-alignment tcolorbox
正文顶部和底部的间距均匀

tcolorbox为什么垂直相对于文本主体没有居中？如何补救？

PS1: 指定的标尺怎么不\DeclareNewLayer显示？

PS2：这是“禁用显示\chapter”。如您所见，我完全放弃了\chapter（不要介意章节计数器、目录等，我稍后会处理它们）。

PS3：不均匀的空间不是由于tcoloborbox页脚造成的，因此有了新标题。还添加了网格。

\vspace{\baselineskip}在第二个之后添加，\vspace*{\fill}在不同设置下都可以完成工作。我不知道为什么首先需要这样做。
