The spacing section makes it possible for you to add a whitespace between certain sections, idealy for when the section above or under it doesnt support spacing settings.
To activate this section you first have to add the section to your page. This can be done in a few small steps.
1) Click on 'add section' which can be found in your left sidebar
2) Scroll down, or search for 'spacing', then click on 'spacing'.
3) Done, your spacing section is added.
