Template documentation[view] [edit] [history] [purge]

This template is used on approximately 9,900 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

This template uses Lua:

Module:Su

Purpose

Template for creating two smaller lines of text on one actual line, this can be used for scientific notations of uncertainty and physics symbols, such as nuclides and particles.

It was named after the  and  HTML tags, which share the first two letters of their name with this template. This template uses the third letter of the name of these tags, p and b, as the name of the argument that drives the output of the top and bottom line, respectively.

Editors beware: these templates use all kinds of hacky tricks to make the output render correctly in a wide variety of browsers. If you plan to make changes to this template, please make sure you verify that this template renders correctly after those changes in all major browsers. This list includes the latest version(s) of Chrome, Firefox, and Safari.

Arguments

p=	The contents of the top line.
b=	The contents of the bottom line.
a=	a=r: right-aligned; `\|a=c`: center-aligned; default is left-aligned).
w=	w=f: fixed-width (monospace), otherwise template inherits the current font and context by default).
lh=	The line height or distance from top to bottom (including top character). Default is 1.2em.

Note on fractions

Usually, when using vulgar fractions it is MOS habit to use &frasl; (⁄) (MOS:FRAC) and {{frac}}. However, in or tags, best use the keyboard slash / for readability in most browsers:

X^1⁄2
_7⁄8 (fraction slash) 文件:Red x.svg

and

X^1/2
_7/8 (keyboard slash)

Line breaks

Unlike and tags, this template does not prevent line breaks between the two small lines and the preceding text. Thus, if this template is used to supply a subscript and superscript over a base symbol, the whole structure has to be enclosed in a {{nowrap}}, or this template should be invoked through another template that takes care of the wrapping in an appropriate way.

Example: {{nowrap|X{{su|p=a|b=b}}}} → X^a
_b
