Template:Infobox
Appearance
Generic infobox base. Wrapper templates should call this rather than writing table markup.
Parameters: class, title, image, imagesize, alt, caption, subtitle, below, and numbered slots headerN / labelN / dataN / rowclassN (N = 1–20).
A row with a label renders as label + data; a row with data but no label spans the full width. Rows with empty data are omitted. Pass a literal pipe as |.
