Yes. Or for things that don't necessarily look the same, but that you 
want to behave as a functional group. For example, you might apply the 
same class to everything on a page that you want to show or hide at the 
same time (using JS or whatever).

Bear in mind also that an element can have more than one class (but not 
more than one ID). So each element can be in zero, one or more of those 
groups, as required.

It might be the simplest thing they could do (until they forgot how they 
were coming up with all those unique IDs and accidentally used the same 
one twice). But that would be some time-consuming and error-prone source 
code to type in, and a pain to maintain.

Designers think about visual differences and similarities all the time, 
that's part of their job. That's why good designs don't generally have 
elements that look *almost* the same, or that *almost* line up... humans 
just don't find them pleasing to look at. Every similarity or difference 
on a well-designed page should be clear and intentional.

Not really... there are probably thousands of teams around the globe 
doing just this sort of thing every day, quite happily.
