This template builds an alternative form of common fractions. It takes one, two or three parameters: the optional integer (may be signed), the optional numerator and the required denominator; in this order. Please do not subst:itute it. This template should not be used in mathematical articles, per MOS:MATH#Fractions.

{{frac|A|B|C}}
A BC (integer, numerator and denominator)
<source lang=html4strict>A BC</source>
{{frac|A|B}}
AB (numerator and denominator)
<source lang=html4strict>AB</source>
{{frac|A}}
1A (denominator only)
<source lang=html4strict>1A</source>

Deactivation and customization

Users who prefer to see fractions inline, e.g. „1 2⁄3“ instead of „​1 23, can turn off the effects of this template by adding the following code to their user stylesheet: <source lang="css">.frac>sup /* numerator */, .frac>sub /* denominator */ {

 vertical-align: inherit/* or baseline*/;
 font-size: inherit/* or 1em*/;
 line-height: inherit/* or 1*/;
 position: inherit/* or static*/;

}</source> These selectors and properties can also be used as a base for custom rendering of vulgar fractions: <source lang="css">/* Stacked Fractions (does not work with three parameters currently) */ .frac

{

 display: inline-block;
 margin-bottom: -0.3em;
 vertical-align: 0.8em;
 line-height: 1.2em;
 text-align: center;
 visibility: hidden;/*hide fraction slash*/

} .frac>sup /* numerator */, .frac>sub /* denominator */ {

 vertical-align: inherit;
 font-size: 85%;
 line-height: inherit;
 position: static;
 visibility: show;

}

.frac>sup::after {

 content: "\A" /* a line break */

} .frac>sub {

 text-decoration: overline;

}</source>

To allow numerical sorting of a column containing fractions, use {{sortfrac}} instead. It is a combination of this template and {{sort}}.
