|
|
|
|
Authors can make elements on a document to be stretched with different
|
|
fonts, e.g.,
|
|
|
|
To request the use of TeX fonts, you can add a <style>...</style> with:
|
|
<mo myfonts="tex">...</mo> with the associated CSS declaration
|
|
mo[myfonts="tex"]::-moz-math-stretchy {
|
|
font-family: CMSY10, CMEX10;
|
|
}
|
|
|
|
To request the use of Mathematica fonts, you can add a <style>...</style> with:
|
|
<mo myfonts="mathematica">...</mo> with the associated CSS declaration
|
|
mo[myfonts="mathematica"]::-moz-math-stretchy {
|
|
font-family: Math1, Math2, Math4;
|
|
}
|
|
|
|
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.
