The meaning of mathvariant=normal is unclear as there is no interpretation

that "corresponds to SMP Math Alphanumeric Symbol characters"
|
|
(http://www.w3.org/TR/2003/REC-MathML2-20031021/chapter3.html#presm.commatt),

|

Authors can make elements on a document to be stretched with different

fonts, e.g.,
|
|
|
|
To request the use of STIX fonts, you can add a <style>...</style> with:
|
|
<mo myfonts="stix">...</mo> with the associated CSS declaration
|
|
mo[myfonts="stix"]::-moz-math-stretchy {
|
|
font-family: STIXNonUnicode, STIXSizeOneSym, STIXSize1, STIXGeneral;
|
|

|
|
|
|
To request the use of Asana fonts, you can add a <style>...</style> with:
|
|
<mo myfonts="asana">...</mo> with the associated CSS declaration
|
|
mo[myfonts="asana"]::-moz-math-stretchy {
|
|
font-family: Asana Math;
|
|
}
|
|
|
|
Of course, if you just want all of the stretchy characters in your
|
|
document to be stretched with your preferred list, you can just do:
|
|
::-moz-math-stretchy {
|
|
font-family: [your-particular-list]
|
|
}
|
|
|
|
Note that like other fonts in the document, users can override this by
|
|
clicking the pref to override document fonts.
