Passing styles to the wrapper div

[deni64k]

Hi, guys!
I struggled into a problem. I have a group of inlined buttons, and one of them opens a modal window.
The problem that the react-portal wraps a button into the div, so the markup becomes broken.
Is there a way to pass styles or add an additional class to the wrapper div?
Also, is it possible to change the wrapper div to the span?
