The various primary and auxiliary infobox templates and navigation templates maintained by the Military history WikiProject are all coded to use a common set of styling characteristics. This is needed primarily because a number of the templates are designed to be stacked together to present the appearance of a continuous block; it is also beneficial for providing a consistent appearance to the entire set of articles within our scope.

The style is controlled by the {{WPMILHIST Infobox style}} template, which generates a number of different codes based on the parameter passed to it.

• {{WPMILHIST Infobox style|main_box}} – produces the CSS class and style parameters for an infobox at a width of 315 pixels.
• {{WPMILHIST Infobox style|main_box_raw}} – produces the raw CSS style parameters for an infobox at a width of 315 pixels.
• {{WPMILHIST Infobox style|main_box_raw_auto_width}} – produces the raw CSS style parameters for an infobox (same as main_box_raw but without width:315px).
• {{WPMILHIST Infobox style|header_bar}} – produces the CSS style parameters for a horizontal header bar in an infobox.
• {{WPMILHIST Infobox style|header_raw}} – produces the raw CSS style parameters for a horizontal header bar in an infobox.
• {{WPMILHIST Infobox style|header_color}} – produces the raw CSS style color attributes for a horizontal header bar in an infobox.
• {{WPMILHIST Infobox style|sub_header_bar}} – produces the CSS style parameters for a horizontal sub-header bar in an infobox.
• {{WPMILHIST Infobox style|sub_header_raw}} – produces the raw CSS style parameters for a horizontal sub-header bar in an infobox.
• {{WPMILHIST Infobox style|image_box}} – produces the CSS style parameters for a standard image & caption block with a bottom border.
• {{WPMILHIST Infobox style|image_box_raw}} – produces the raw CSS style parameters for a standard image & caption block with a bottom border.
• {{WPMILHIST Infobox style|image_box_plain}} – produces the CSS style parameters for a standard image & caption block without a bottom border; this is typically used when the image block is placed immediately above a header bar, or at the bottom of the infobox.
• {{WPMILHIST Infobox style|image_box_plain_raw}} – produces the raw CSS style parameters for a standard image & caption block without a bottom border; this is typically used when the image block is placed immediately above a header bar, or at the bottom of the infobox.
• {{WPMILHIST Infobox style|internal_border}} – produces the raw CSS style attributes for a border between parts of the same infobox section.
• {{WPMILHIST Infobox style|section_border}} – produces the raw CSS style attributes for a border between different infobox sections.
• {{WPMILHIST Infobox style|nav_box}} – produces the raw CSS style attributes for a collapsible navigation template at a width of 315 pixels.
• {{WPMILHIST Infobox style|nav_box_child}} – produces the raw CSS style attributes for a collapsible navigation template (same as nav_box but at a width of 305 pixels and without margin-left:1em).
• {{WPMILHIST Infobox style|nav_box_wide}} – produces the raw CSS style attributes for a full-width collapsible navigation template.
• {{WPMILHIST Infobox style|nav_box_header}} – produces the raw CSS style attributes for the header bar in a collapsible navigation template.
• {{WPMILHIST Infobox style|nav_box_wide_header}} – produces the raw CSS style attributes for the header bar in a full-width collapsible navigation template.
• {{WPMILHIST Infobox style|nav_box_label}} – produces the raw CSS style attributes for a row label in a collapsible navigation template.

A sample template using some of these options can be seen at right. From the top, it includes:

1. The main header_bar in a table heading cell.
2. A sub_header_bar in a normal table cell.
3. An image_box.
4. Two normal fields with labels.
5. A secondary header_bar in a heading cell.
6. A pair of cells divided by an internal_border.
7. A cell with a section_border at the top.
8. Another secondary header_bar in a heading cell.
9. An image_box_plain.

More sophisticated samples of the code can be found by examining the actual infoboxes used by the project.
