Skabelon:Varserif
{{{1}}}
Denne skabelon bruges af forskellige tekniske skabeloner, for at få det korrekte semantiske kode. Forklaring ses nedenfor, det meste er på engelsk (fra den engelske Wikipedia):
This template is to help facilitate the displaying of variable names (in mathematics, computer source code, etc.) with the semantically correct <var>...</var>, which also renders the variable in italics, as is customary, and to do so in a serif font. This is specifically for the use of the characters "I" (upper-case i) and "l" (lower-case L), which in many sans-serif fonts can be difficult to distinguish. The template also very slightly adjusts the font size of the enclosed variable, to account for typical difference in x-height between non-fancy serif (e.g., Times and Times New Roman) and sans-serif (e.g. Arial and Helvetica) typefaces. The template should not be used generally, but only for "I" and "l", and perhaps other cases where a known visual ambiguity can be shown to exist in common sans-serif fonts for readers without acute vision. It is recommended to use {{var|1}} rather than {{varserif|1}} for "1" (numeral one), as it is usually more clearly distinguishable from "I" and "l" in sans-serif than serif fonts.
{{Varserif}} need not be used for variables that simply contain "I" or "l", only for cases in which readers are likely to be unable to distinguish them visually.
The {{varserif}} method is preferred to simply italicizing and using inline style to specify the font, for accessibility, content/presentation separation, semantic Web, and metadata reasons; XHTML's <var> element has semantic meaning, while simple font changes like italicizing does not.
Because the font styling in the template is done entirely with CSS, it has no effect at all upon content semantics, nor does it change the output for users of screen reader software.
Eksempel:
{{varserif|I}}
outputs:
<var style="font-size:118%;font-family:serif;">I</var>
which renders as:
- I
- Sammenligning
{{var|I}}= I{{var|l}}= l{{var|1}}= 1{{varserif|I}}= I{{varserif|l}}= l{{varserif|1}}= 1
Please note that {{varserif}} is not a panacea; its treatment of the numeral "1" is easily mistaken for the letter "l" (lower-case "L") in many serif fonts.
- Recommended usage
{{varserif|I}}= I{{varserif|l}}= l{{var|1}}= 1{{var|variable}}for any other variable
