What is the descendant combinator in CSS?

Descendant Combinator in CSS

The descendant combinator in CSS is a space character ( ) that selects all elements that are descendants of a specified parent element, at any depth in the DOM tree.

Key Points
  1. 1

    Syntax: A B – selects all B elements inside A regardless of depth.

  2. 2

    It applies styles to nested elements without needing direct parent-child relationship.

  3. 3

    Useful for targeting elements deeply nested within a container without adding extra classes.
