Hiding Empty Elements with CSS ::empty Pseudo-Class

Problem: I needed to hide elements that have no child content (text, images, or elements) on the page using a simple CSS solution

Solution: I used the ::empty pseudo-class, which selects elements that have no child nodes, and applied display: none to hide them when they are empty.

.div-to-check::empty {
   display: none;
}

Keywords: CSS ::empty pseudo-class, hide empty elements, CSS display none, dynamic content styling, hide elements with no content, empty element selector.
