This is a documentation subpage for Wikipedia:Wikipedia Signpost/Templates/Signpost-header. It may contain usage information, categories and other content that is not part of the original wikipedia page.

This is invoked as such:

From Template:Signpost archive:

• {{Wikipedia:Signpost/Template:Signpost-header|[[Wikipedia:Wikipedia Signpost/Archives|← Back to Archives]]|{{date|{{{2}}}|dmy}}|[[Wikipedia:Wikipedia Signpost|View Latest Issue]]}}

From article pages, like Wikipedia:Wikipedia Signpost/2023-08-01/Humour:

• {{Wikipedia:Signpost/Template:Signpost-header|||}}

From Wikipedia:Wikipedia Signpost:

• {{Wikipedia:Signpost/Template:Signpost-header|{{Str left|{{Wikipedia:Wikipedia Signpost/Templates/Issue|2}}|9}}|{{date|{{Wikipedia:Wikipedia Signpost/Templates/Issue|1}}|dmy}}|{{Str right|{{Wikipedia:Wikipedia Signpost/Templates/Issue|2}}|10}}}}

In general, as you can see above, it takes three unnamed parameters:

• {{{1}}}, for text on the left
• {{{2}}}, for text in the center
• {{{3}}}, for text on the right

It summons a TemplateStyles from Wikipedia:Wikipedia Signpost/Templates/Signpost-header/styles.css and uses it to style and create the Signpost header.

It uses these divs and these classes, contained in this order:

• signpost-header nomobile noprint (container div, no content in the div itself)
  • signpost-header-heading (File:Signpost2.svg)
  • signpost-header-subheadings (container div, no content in the div itself)
    • signpost-header-volume (volume number, on left, e.g. "Volume 19")
    • signpost-header-issue (issue number, on right, e.g. "Issue 16")
    • signpost-header-date (date of issue, in center, e.g. "15 August 2023")
  • signpost-header-subsubheadings (empty div -- this can be used for whatever nonsense by the frontend)

Note that signpost-header-volume, signpost-header-issue and signpost-header-date can actually just be whatever random stuff -- and, in fact, some templates (like {{Signpost archive}}) do call the header template with stuff other than volumes and issues in those locations.

Note again -- very importantly -- the following.

That's a totally different template that exists for some reason (?)
