First let's identify what is the difference between classes and id. ID - a unique attribute for an element. 2 elements cannot have the same id. Selectors usually have #ID_NAME syntax class - Can apply to many elements . not unique. Selectors usually have .CLASS_NAME syntax. Id selectors are much more powerful than class and they can override properties defined in classes. This doesn't mean that you have to use IDs everywhere. You can use it when an element is going to be unique than others. Classes are useful when applying styles or scripts to elements where common behaviours are expected.
