I have always thought Labels are the worst thing ever in Moodle, even before Moodle developers moved to useing Bootstrap platform.
It might be the way it is created, but I dare say too it could also be the Text Editor. I like to use TinyMCE but Moodle‘s default editor is ATTO.
I‘ll take a look at the Lable Module and see it it can be changed.

Hi Mary,
very kind of you to reply my..."label html editing dilemma".
I am trying to make a label (responsive), by using inline css, flexbox properties, but it´s only giving me headaches so far.
You´re probably right that:
- maybe the labels structure don´t wrap with a boostrap class whatever you are feeding via ATTO. And therefore it cannot apply the BS4 grid classes. (In short it don´t work)
- maybe ATTO cuts down classes but... nope. What I put in the editor, it´s what the code editor (<>) shows when you try to edit the content. So I guess the code goes correctly into de Moodle DB.
I will keep trying to make it work, maybe I shoud try good&old table markup.
Please if you found something on the "label's editing paradox", please share your thoughts on it.
Regards,
M.
I’ll see if I can come up with a fix for this...
but don’t hold your breath. 
LOL
