Does BEM extend to ids?

[glennsimon]

What is the recommendation for id naming? I would assume that an id (#) would have the same rules as a block, but is BEM intended only for class naming and not ids?

[iamstarkov]

BEM recommends to avoid id usage as much as possible

[glennsimon]

Thank you @iamstarkov. Why does bem recommend avoiding using IDs?

[iamstarkov]

because of very high specificity
