ID's are unique

  • Each element can have only one ID
  • Each page can have only one element with that ID

Classes are NOT unique

  • You can use the same class on multiple elements.

  • You can use multiple classes on the same element.

The id is an identifiant which is supposed to be unique amongst its siblings.

The class is not related to uniqueness.
