Why we can only use or select the class or id which are inside <div> html tag?

Question

I cannot select the class outside the <div> tag to style. Any answer would be appreciated.

Answer 1

Khun Tee Bwar for css, you're right, the selector can only select his own, sibling or child elements, not parent element.

Answer 2

You could use parentElement.
parentElement is the parent element of the current node. It return a DOM Element object or return null if no parent element exists.

Eg

if (divNode.parentElement) {
divNode.parentElement.style.color = "red"; // set text color of parent node
}
