Are classes the same in all languages including HTML?

Question

Are the classes in C++ the same as in CSS? Do they have the same function?

Answer 1

No. Neither HTML nor CSS are programming languages. Classes in CSS are just used to style multiple elements.

Answer 2

From cplusplus.com: Classes are an expanded concept of data structures: like data structures, they can contain data members, but they can also contain functions as members.

An object is an instantiation of a class.
