Class or Id?
I have a very rudimentary question. When you are building a base layout for a webpage, why do people usually give a class rather than an id, when you only use that class one time. (For example, class="main-logo", instead of id="main-logo"). Isn't it more efficient to select ids than classes. Could someone please answer this very basic question?

Class selector in CSS is used to select multiple elements in your HTML, they share the same class attribute. However, ID is unique, meaning you can select only one element at a time using an ID selector.
