Hello there,

From your site dashboard, navigate to Appearance > Customize > General. Enter zero to the two options provided.

If this isn’t enough, try adding the below extra CSS code to Appearance > Customize > Additional CSS.

.page-wrap .content-wrapper {
  padding-top: 5px !important;
  padding-bottom: 5px !important;
