: How to make elegant separation between technical proof and its meaning? I would like to have a visual separation between a normal text (above the line) and its explanation (under the line) so

@RJPawlick971

I don't know if I understand the full context but here's my interpretation. I think there are two things that need to be accomplished.


Visually stylize the proof/explanation area differently than the rest of the content.
Separate the content from the proof/explanation.


I'd suggest judicious use of white space...both vertically (space between paragraphs/sections) as well as horizontally (indent the proof/explanation area).

A line works well, but it can be subtle. You don't need to make it large and dark. Example:

I agree with Random O'Reilly. Especially in regards to the justified text. Only alternative I would also consider for the separator is a double line instead of a single.

Here I used the same size double lines as in your equal sign:

@Rivera951

If I were you, I would keep it in essence, but differentiate by either/or:


Make the text line italic, bigger font or bold
Make the distance from text line to equation bigger


I would remove the left justified on the text lines. It looks bad when the variation in spaces between the words gets so pronounced.



Edit I:

By removing the left justified, I mean that this sentence gets very weird spaces between the words.


You see they are placed so that the sentence takes up the whole space. The sentence below the equations are not left justified, so that looks better.



Edit II:
As to how big a gap between text and equation;... well. The same as the distance between your paragraphs.

These may be of interest:

Font for section and subsections, titles in scientific thesis

Layout for technical documents

How much space between two paragraphs

Readability as a function of measure and leading
