Reduce font size of price for products on collection pages only

[bragabags]

Hi, I'm trying to reduce the font size of prices for products on my site's collection pages only. I've searched the internet for coding solutions and have tried to implement all of the ones I found that applied to my situation, and nothing has worked. I've added other code to my site recently successfully.. So I'm not sure what I'm doing wrong. Would appreciate any assistance, thank you!
