Reduce height of space above my Custom Headlines - globally

[TownleyGrammar]

I want to reduce height of space above my Custom Headlines as in post linked below, but want to do it globally on all Custom Headlines on the site, where would I add the class man to achieve that?

@Joao

Please add the class man to the class box of your custom headline element.

Hi there,

If you want to Classic Custom Headline element not to have any space around it, please add this code to the Global CSS:

.h-custom-headline {
    margin: 0 !important;
}

Hope this helps.
