Subject of the enhancement
Within the framework and authoring tool, a user is required to manually type out the custom class(es) required for increasing, decreasing, or removing the block top and / or bottom padding.
This custom class has to be applied to the _classes field on the block or corresponding field within the authoring tool.
Your environment
Expected behaviour
The application of the block padding custom classes could be optimised by converting the options to a drop down selection, similar to the vanilla's background image styles property.
