Custom class names or class prefix

@onokazu commented on Jun 11, 2018, 3:10 AM UTC:

We're using Bootstrap with all CSS class names prefixed with something like "vendor-bs-", so for example the .btn class is .vendor-bs-btn in our application. It would be great if there is an option to specify CSS class names or a class prefix to be used with the library.
