Need To Select A Block ID For CSS Customization

Hello, I want to select a specific and unique block ID on Shopify for all my products. The selector that I want to modify is in the below screenshot.

I tried the following:

.product-single__meta .product-block > div:nth-child(1){
max-width:150px !important;
margin-left:0px !important;
}

This works. However, it also affects two other elements on the same page which I don’t want. That’s why the selector is wrong and is not specific to that block. When inspecting the element and doing the changes, it works which proves that the selector is not right. Any help on how to solve this is much appreciated. (:

I solved the problem. Dismiss.

How did you do it? I’m trying to do the same thing..
