I feel dumb.. Why is my "header" div not being selected? It's background color is not being changed. I am learning about the + operator so I am not looking for a different selector.

E + F an F element immediately preceded by an E element

$("#divA + div").css("background-color", "red");

Html

<div id="divA">
        <div>
            Header</div>
        Lorem Ipsum is simply dummy text of the 
        printing and typesetting industry.
</div>

Thanks!
