Font plugin default. Any way to set it to inherit font-family of child theme?

Accordion plugin font-family is set inline with a handful of alternates within the plugin settings.

Is there a way to set the font-family to inherit the child theme’s font for all accordions I create with this plugin?

I’m not sure if one can even override inline css that within a wordpress plugin’s style.css. I couldn’t find the answer googling and searching forums. I’ve tried to hack away at the css but am getting know where.

.classname {
font-family: inherit;
}

Any help really appreciated.
