How do i get the css class names of the html blocks i added to my impulse theme?

[Clarissaaaaaaaa]

I added three custom HTML blocks:

This is how they look like in the product page:

This is the code of one of these HTML blocks:

Now, I want to remove the spacing below of these 3 HTML blocks.

But the bottom margin is applied to the container of each these HTML blocks.

So I need to go outside of this HTML blocks, and onto the Product page CSS.

But I would need the CSS Class Names of each of these 3 HTML blocks.

To call them in the Product page css and remove the bottom-margin.

Although there is a default class name for them which is “product-block”,

When I use the class name “product-block” it edits all the other blocks as well.

I only want to edit these 3 HTML blocks I added.

So I would need their class names, how do I know/where do I get their class names?

Thank you so much.

Hey @Millennium3 , thanks for your reply. But my question was where/how do I get the class name?
Not add one.

Thanks.
