Template:Frac/doc
 | This is a documentation subpage for Template:Frac. It may contain usage information, categories and other content that is not part of the original template page. |
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 B⁄C (integer, numerator and denominator)
- <source lang=html4strict>A B⁄C</source>
{{frac|A|B}}- A⁄B (numerator and denominator)
- <source lang=html4strict>A⁄B</source>
{{frac|A}}- 1⁄A (denominator only)
- <source lang=html4strict>1⁄A</source>

Deactivation and customization
Users who prefer to see fractions inline, e.g. „1 2⁄3“ instead of „1 2⁄3, 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}}.
