JQuery child selector selects all the elements that are child of parent element in the set of matched elements. It represents the child element which is obtained from selector. It selects all the child elements that are defined by parent selector. The child selector searches for children elements in the document object model structure and constructs new object from the set of matching elements. The child selector accepts the elements that are of same type that we can pass to the $() function. It’s written using greater than symbol (>) and it must appear between two other selectors.

$( "div.myclass > span" ).css("border","2px groove orange");
