What sets id and class apart from each other?

I understand that for id we need to use the '#' symbol and for class '.' symbol. However, I am unsure of the specific purposes of both class and id in styling CSS. Can someone provide clarification on when I should use id and when I should use class? Are there any significant differences between the two?

Answer №1

Uniqueness of IDs

  • IDs are unique to each element
  • Each page can have only one element with a specific ID

Classes and their non-uniqueness

  • Multiple elements can have the same class

  • An element can have multiple classes assigned to it.

Answer №2

Each id is meant to be distinct from its sibling elements.

Uniqueness is not a characteristic of the class attribute.
