How to reduce/remove spacing in Sydney

Spacing (padding) in Sydney may exist in a number of ways:

1. Spacing between the header (or footer) and the actual page content: you can customize it by going to Appearance > Customize > General > Page wrapper – top padding (bottom padding);
2. Spacing between rows (created with the Page Builder plugin): you can customize it by editing your page builder row from Edit row > Row Styles > Layout > Top/bottom padding;
3. Spacing around a widget (added in a Page Builder row): you can customize it by editing your widget from Edit widget > Widget Styles > Layout > Padding.
