How do combinators affect CSS inheritance and cascade?

Combinators and Their Effect on Inheritance and Cascade

CSS combinators do not change the rules of inheritance or the cascade themselves. They control which elements a selector matches based on DOM relationships, but once an element is matched, normal inheritance and cascade rules apply.

Key Points
  1. 1

    Combinators (descendant, child, adjacent sibling, general sibling) define which elements the style applies to, not how properties are inherited.

  2. 2

    Matched elements receive the specified styles, and these styles participate in the normal cascade with specificity, importance (!important), and order of appearance.

  3. 3

    Properties that naturally inherit (like color or font-family) still propagate to children unless overridden, regardless of combinators used.

  4. 4

    Using complex combinators can increase specificity, potentially overriding other rules in the cascade.
