Sections, paragraphs, lists and lines

What it looks like	What you type
Start your sections with header lines: New section Subsection Sub-subsection	NaodW29-pre6a1b912164ec257700000001
Newline: A single newline has no effect on the layout. But an empty line starts a new paragraph. (<p> disables this paragraphing until </p> or the end of the section) (in Cologne Blue two newlines and a div tag give just one newline; in the order newline, div tag, newline, the result is two newlines)	NaodW29-pre6a1b912164ec257700000002
You can break lines without starting a new paragraph. Sufficient as wikitext code is <br>, the XHTML code <br /> is not needed, the system produces this code.	NaodW29-pre6a1b912164ec257700000003
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 the list. Of course you can start again.	NaodW29-pre6a1b912164ec257700000004
Numbered lists are also good very organized easy to follow A newline in a list marks the end of the list. New numbering starts with 1.	NaodW29-pre6a1b912164ec257700000005
You can even do mixed lists and nest them like this or have newlines inside lists	NaodW29-pre6a1b912164ec257700000006
You can also break lines inside lists like this	NaodW29-pre6a1b912164ec257700000007
Definition list  list of definitions item  the item's definition	NaodW29-pre6a1b912164ec257700000008
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.	NaodW29-pre6a1b912164ec257700000009
NaodW29-pre6a1b912164ec25770000000A WARNING If you make it wide, you force the whole page to be wide and hence less readable. Never start ordinary lines with spaces. (see also below)	NaodW29-pre6a1b912164ec25770000000B
Centered text.	NaodW29-pre6a1b912164ec25770000000C
A horizontal dividing line: above and below. Mainly useful for separating threads on Talk pages.	NaodW29-pre6a1b912164ec25770000000D

Summarizing the effect of a single newline: no effect in general, but it ends a list item or indented part; thus changing some text into a list item, or indenting it, is more cumbersome if it contains newlines, they have to be removed; see also w:Wikipedia:Don't use line breaks.
