I am trying to make some notes for my math class, and I would like to organize them in the following way: I first want to split the page with a vertical line, and have definitions on the left, theorems on the right. Secondly, I would like to split the page by horizontal lines, which split the material along lectures (illustration at the bottom). Using the answer here, I've managed to split the page by a vertical line. However, I can't figure out the horizontal lines. Any help is greatly appreciated!
Definitions | Theorems
Lecture 1 ....| Lecture 1
Def 1...........| Thm 1
Def 2...........| Thm 2
Def 3...........|
.---------------------------------
Lecture 2....| Lecture 2
Def 1...........| Thm 1
Def 2...........| Thm 2
.---------------------------------
and so on.
minipageenviornments or the one using theparallelpackage? Please also add some more information on the desired alignment. Does one "lecture" part span multiple pages or will two of them always fit onto a single page perfectly? Do you always want to vertically align "Def" and "Thm"? Where should the second theorem start, if the first theorem is short, but the first definition is long?... – leandriis Sep 15 '20 at 17:40\hruleto draw a horizontal line across the textwidth. – leandriis Sep 15 '20 at 17:41
