How to customize acordion description as monospace

I was wondering how to make the description section of my accordion as monospace. The options only include Paragraph 1, 2, 3 style. I think that a custom-css might be the easiest way, not sure?...

Add to Design > Custom CSS

.sqs-block-accordion .accordion-item__dropdown--open * {
	font-family: monospace !important;
}

Thank you, I tried this but it still looks like this: 

Whereas, I want it to look like this text: 

I thought you want accordion text font to Monospace font

Can you share link to page where you use "Monospace" We can check its style easier?
