Template:Spoiler

This template hides story content in a spoiler box. The box shows a short warning and a Show link; the content stays hidden until the reader opens it. It is the wiki's way of marking story spoilers (see How to contribute#Spoilers).

This box is closed until you open it.

This is what a spoiler box looks like. The text inside stays hidden until you select Show.

Usage

Short content

{{Spoiler|mission=5|1=Hale gives the order to fall back to the hall.}}

Always write the content as 1=. Without it, an equals sign anywhere in the text (for example inside a link or a style) breaks the template.

Long sections

For a section with paragraphs, lists or tables, use the pair {{Spoiler start}} and {{Spoiler end}} instead. It takes the same parameters, and the content between the two is ordinary wikitext:

== Story ==
{{Spoiler start|mission=5}}
First paragraph.

* A list item.
{{Spoiler end}}

Keep section headings outside the box. A heading inside a closed box still appears in the table of contents, but following it does not open the box.

Inside an infobox

Add compact=yes for a one-line warning, which fits a narrow table cell:

| objectives = {{Spoiler|mission=5|compact=yes|1=<ol><li>Hold the first assault.</li></ol>}}

Use HTML lists (<ol><li>) inside a template parameter. Wikitext lists need a new line, and table syntax (|) cannot be used there at all.

Parameters

Parameter	Meaning
`1`	The hidden content. Write it as `1=...`.
`mission`	Optional. A mission number; the warning then reads "Story spoilers: Mission 5".
`about`	Optional, used when `mission` is not given. Free text for the warning, for example `about=Missions 1-10`.
`compact`	Optional. `yes` leaves out the second line of the warning.

How it works

It uses only MediaWiki core: the mw-collapsible mw-collapsed classes, which the software turns into a closed box with a Show / Hide link. No extension is needed.
The colours use the skin's own colour variables, with fixed fallbacks, so the box stays readable in light and dark display modes.
Readers who browse without JavaScript see the content open. The warning line is still shown above it.
In the visual editor a spoiler box appears as one block. To edit the text inside it, use Edit source.
This template and its two partners are protected, because every story page depends on them.

When to use it

Wrap anything that tells what happens in the Story campaign: mission plots, objectives that give away events, what happens to characters, and endings.
A mission's name, number, chapter and map are not spoilers.
Pages about mechanics, units and buildings should not need it.

Hides story spoilers in a closed box with a warning and a Show link. For long sections use Spoiler start and Spoiler end.
