Blog Layout/Masonry - Padding Around Posts

Is there a way to reduce the amount of space between where the blog posts (including single-page posts) start and the header area/header widget area?

Hello there,

Try adding the below CSS code to Appearance > Customize > Additional CSS from dashboard.

    .page-wrap {
      padding-top: 10px;
      padding-bottom: 10px;
    }
