BEM global img{} rule?

css

Is using such code BEM?

img {
max-width: 100%;
height: auto;
}

Answer 1

BEM does not use tag and ID selectors. Block and element styles are described through class selectors.

Answer 2

Yes, why not?
This is a generic style that is not actually a yulok element or modifier.
Similarly, if you need the b tag to be everywhere not the 900th, but the 700th, will you create a class for it?
