LaTeX New Line - How to Insert New lines and White Spaces in LaTeX Documents
Newlines and whitespaces are often mistakenly used in order to format a document and position (text) elements on a certain position of the page.
For example, it is quite popular to use newlines to adjust the space between a heading and a paragraph. Needless to say that this makes it hard to manage the formatting of a longer document. You need to go through to whole document over and over again to check if everything is still where it it supposed to be.
"What you see is what you mean" systems like LaTeX or MonsterWriter usually ignore new lines or whitespaces. Or at least condense multiple following new lines or whitespaces into a single one. The example LaTeX code you see in [listing-1] and [listing-2] are producing the exact same PDF.
