MathJax doesn't have a method to specify the bevelled attribute on <mfrac> directly from TeX, but you could define your own macro that would accomplish that. For example
<html>
<head>
<title>Add Bevelled Fraction Macro</title>
<script type="text/x-mathjax-config">
MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () {
var MML = MathJax.ElementJax.mml,
TEX = MathJax.InputJax.TeX;
TEX.Definitions.macros.bfrac = "myBevelFraction";
TEX.Parse.Augment({
myBevelFraction: function (name) {
var num = this.ParseArg(name),
den = this.ParseArg(name);
this.Push(MML.mfrac(num,den).With({bevelled: true}));
}
});
});
</script>
<script type="text/javascript"
src="../MathJax/unpacked/MathJax.js?config=TeX-AMS_HTML">
</script>
</head>
<body>
<p>A bevelled fraction: \(\bfrac{1}{2}\)</p>
</body>
</html>adds a \bfrac macro that you can use to get a bevelled fraction. The spacing will be better than trying to use \! and super- and subscripts to manage it by hand.
