Using Descendant and Child Combinators in CSS
You can use the descendant combinator (space) to select all <p> elements inside a <div> regardless of nesting depth, and the child combinator (>) to target only direct children, such as <li> elements inside a <ul>.
Descendant combinator (A B) selects all B elements nested anywhere inside A.
Child combinator (A > B) selects only B elements that are direct children of A.
These combinators allow precise targeting of elements based on DOM relationships without adding extra classes or IDs.
Using the correct combinator improves maintainability and performance by avoiding overly broad selectors.
