Text formatting

Bold and italics

Emphasis uses runs of apostrophes:

You write	You get
`''italic''`	italic
`'''bold'''`	bold
`'''''bold italic'''''`	bold italic

Single apostrophes are never markup — don't, rock 'n' roll, and [[Rock 'n' Roll]] all pass through untouched. Only a run of two or more apostrophes is interpreted.

Details worth knowing:

Emphasis is per-line. A '' opened on one line will not carry to the next — the parser closes it at the end of the line. Unclosed markup is auto-closed, so unclosed ''italic still renders the rest of the line in italics rather than showing stray apostrophes.
Four apostrophes render as one literal apostrophe followed by bold.
To show literal apostrophe runs, use nowiki.

Paragraphs and line breaks

Consecutive lines of text join into one paragraph.
A blank line starts a new paragraph. Extra blank lines don’t add extra space — runs of blank lines collapse.
A newline inside a paragraph does not become a line break. For a hard break, write the HTML tag  .

Horizontal rule

Four or more dashes at the start of a line:


----

Preformatted text

A line that starts with a space becomes preformatted (monospace, preserved spacing); consecutive space-prefixed lines join into one block:


 this line is preformatted
 so is this one

For code with syntax highlighting, prefer the syntaxhighlight tag.

Because a leading space means “preformatted”, be careful with markup that can leave a space at the start of a line — for example a template that doesn’t exist expands to nothing, and the space after it can turn the rest of the line into a preformatted block.

Inline HTML

A curated set of HTML tags is allowed and can be mixed with wiki markup — , , , <s>, , <div>, semantic tags, and more. Anything outside the allowlist is escaped and shown as literal text, never silently dropped, so you can always see what happened. Event handlers (onclick=…) are always removed. The full generated lists live in HTML & CSS.
