Reducing space between post titles/metadata and content on front page

Hi,

I would like to reduce the space between a post’s title and metadata on the frontpage. I can do this already for single posts with the following Additional CSS code:

.singular .entry-header {
    padding-top: 2rem !important;
    padding-bottom: 3rem !important;
}

but I am unsure of how to do this for multiple posts that are displayed on the front page of the site. Any help greatly appreciated.

Thanks,

Martyn
