Question about blocs

One of our department are switching over to a CMS that uses bootstrap 4 out of the box so I am looking for a Bootstrap GUI editor and I some question about this editor.

Will this editor publish custom css that can be applied to an out of the box bootstrap or it contains a modified bootstrap framework?

Thank you

Is this the wrong place to ask pre-sales question? Am I posting it in the wrong location?

Thank you

I believe you can only work with content generated by Blocs. Yes it’s Bootstrap, but it cannot import and edit projects created using other sources.
