CSS Selectors

Selectors are patterns that match elements in a document tree. Understanding specificity and combinators is essential for writing maintainable CSS.

Selector Types

  • Type selectors — div, p, span
  • Class & ID — .card, #header
  • Combinators — descendant, child (>), sibling (~, +)
  • Pseudo-classes — :hover, :first-child, :nth-of-type()
  • Pseudo-elements — ::before, ::after, ::placeholder
