修改康奈尔笔记模板

Question

我正在尝试修改康奈尔笔记模板满足我的具体需求。

1. 有没有办法让背景上的红线在章节和小节标题之前和之后断开？

   我查看了背景文档，没有找到可以执行此操作的选项。tikz 是否有选项？

2. 我必须进行哪些更改才能使红色\topic 框始终与第一个蓝色框对齐？

\documentclass[a4paper]{article} 
\usepackage{tcolorbox}

\title{
    \vspace{-3em}
    \begin{tcolorbox}[colframe=white,opacityback=0]
        \begin{tcolorbox}
            \Huge\sffamily Cornell Notes on Something   
        \end{tcolorbox}
    \end{tcolorbox}
    \vspace{-3em}
}

Answer 1

更新在后续问题之后

paracol我建议使用能够满足两个要求的包来编写更简单的代码。

使用左栏插入问题\question {<question text>}

\question以 结尾\switchcolumn，因此后面的注释将自动移至右列。使用 在右列中插入任意数量的注释\note{<note text>}。

当同一节中有多个问题时，\switchcolumn*在下一个问题之前插入以同步列。可以添加一个小的垂直空间来分隔问题\注释组。
