Hi, how do I find out what classes affect the built in forms in Blocs? I specifically want to format the “The field is required” message, but being able to format other elements would be great.
Make a class called alert-warning for the required fields and set fonts and background to your needs.
You don’t have to employ it to the fields directly.
Just build the class.

Thanks for that, I shall try it.
I guess my question can be expanded to ask
How would I find this out - other than asking on the forum. Do I need to learn Bootstrap as well as Blocs 
I believe the official Bootstrap page has a list of inbuilt classes - however, last time I looked (admittedly, a while ago) it would only make sense to people who knew what they were looking for, the label explanations what threw me off just trying to understand what they related to.
