-7. **Optional** One method of adding global parameters to siunitx formatting is to add them to the MathJax configuration file.  For example, if you wanted all fractions on that page to display as numerator over denominator (instead of inline with a slash character), you would use the `per-mode = fraction` setting.  You can add this directly to the tex object in the configuration.  You must convert the property name from dash-case to camelCase (remove dashes and capitalize the first letter after each dash, i.e. `list-pair-separator` becomes `listPairSeparator` ).

For example, if you wanted all fractions on that page to display as numerator over denominator (instead of inline with a slash character), you would use the `per-mode = fraction` setting.  You can add this directly to the tex object in the configuration.  Since LaTeX options are dashed-case, most of the option names need quotes around them.
