Accordion Slider custom height adjustment

I use the Accordion slider in three different pages on my website. However I’d like the change the height of it on just one of them but not effect all three.

I’ve seen that the css code below effects the height perfectly. But I would like it to only effect one of my sliders.
#top .aviaccordion {
height: 100px;
}

Under the Accordion Slider settings called “Developer Settings”, I’ve added a “Custom CSS Class” of
recognitionaccordion

How do I add it to the css above to get that one slider height adjusted the way I’d like?

Or is there a different way to go about this. Any assistance you can provide would be greatly appreciated. Thank you for your time.
