Template:Infobox

One infobox for everything: projects, people, hardware, models, concepts. Every field is optional and empty rows are hidden.

Usage

{{Infobox
| title      =            <!-- defaults to the page name -->
| image      =            <!-- file name, without "File:" -->
| image_size =            <!-- defaults to 220px -->
| caption    =
| alt        =
| header1    =            <!-- optional section heading above row 1 -->
| label1     =
| data1      =
| label2     =
| data2      =
<!-- ... up to label30 / data30, header1 - header30 -->
| below      =            <!-- optional footer line -->
}}

A row shows only when its dataN is filled in.
dataN without labelN spans the full width.
headerN puts a section heading before row N. Numbers don't need to be consecutive, so you can leave gaps for rows you'll add later.
