A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function (used internally to compare different versions of a page).

But an empty line starts a new paragraph.

• When used in a list, a newline does affect the layout (see below).

You can break lines
without starting a new paragraph.

• Please use this sparingly.

You can break lines<br>
without starting a new paragraph.

• Lists are easy to do:
  • Start every line with a star.
    • More stars means deeper levels.
      • A newline in a list

marks the end of a list item.

• An empty line starts a new list.

* Lists are easy to do:
** Start every line with a star.
*** More stars means deeper levels.
**** A newline in a list
marks the end of a list item.

1. Numbered lists are also good
   1. very organized
   2. easy to follow

Definition list 

list of definitions

item 

the item's definition

another item

the other item's definition

• One item per line; a newline can appear before the colon, but using a space before the colon improves parsing.

; Definition list : list of definitions
; item : the item's definition
; another item
: the other item's definition

A colon indents a line or paragraph.

A manual newline starts a new paragraph.

• This is primarily for displayed material, but is also used for discussion on Talk pages.

IF a line starts with a space THEN
it will be formatted exactly
as typed;
in a fixed-width font;
lines won't wrap;
ENDIF
this is useful for:
* pasting preformatted text;
* algorithm descriptions;
* program source code;
* ASCII art;
* chemical structures;

• WARNING: If you make it wide, you force the whole page to be wide and hence less readable, especially for people who use lower resolutions. Never start ordinary lines with spaces.

A horizontal dividing line: this is above it

and this is below it.

• Mainly useful for separating threads on Talk pages.
• Also used to disambiguate within an article without creating a separate page.
