Learn Typography by Building a Nutrition Label - Step 27

In step 26 we create a div with class=“divider lg”:

Yet, in step 27 we’re adding a ".lg "selector instead of something like “.divider lg”(which I understand would hypothetically look for “lg” element in “.divider” class). Doesn’t the same value in class=“divider lg” need to be used in CSS? What’s the catch here?

Nvm. We’re just using mutiple classes there, and “divider” was already defined earlier. Don’t know how to delete this post.
