This is a documentation subpage for Template:Blackboxwarning.
It contains usage information, categories and other content that is not part of the original template page.


{{blackboxwarning}} creates an information box intended for very strong warning messages. The box will show at the position on the page where you put the template, and stretch horizontally to fill the width of the available space and vertically depending on how many rows of text are needed. The text inside the box is centred.

To use the template, type {{blackboxwarning|custom text}}.


There is only one parameter, which is unnamed (below called 1). The text inside the box can be formatted using wiki-code.

Custom text

1: Custom text

This parameter is used for entering the message text. It is not strictly required, but strongly recommended, since the template is more or less useless without it. The parameter is unnamed, so no parameter name needs to be entered.
