By default, Page Builder adds a margin below your rows. For most simple layouts, this is ideal, but what happens if you want a slightly different layout, where the rows are touching.
To achieve this, you just need to remove the bottom margin on a given row.
By default, a rows bottom margin is blank. This means it’ll take on the globally set default value. However, entering 0 in this field, will completely remove the margin.
Another option is to change this setting globally. Navigate to SettingsPage Builder – under the Layout section, set Row Bottom Margin to whatever you need it to be.
