The :scope CSS pseudo-class represents elements that are a reference point for selectors to match against.
/* Selects a scoped element */
:scope {
background-color: lime;
} Currently, when used in a stylesheet, :scope is the same as :root, since there is not at this time a way to explicitly establish a scoped element. When used from a DOM API such as querySelector(), querySelectorAll(), matches(), or Element.closest(), :scope matches the element you called the method on.
:scope
In this simple example, we demonstrate that using the :scope pseudo-class from the Element.matches() method matches the element on which it's called.
let paragraph = document.getElementById("para");
let output = document.getElementById("output");
if (paragraph.matches(":scope")) {
output.innerText = "Yep, the element is its own scope as expected!";
} <p id="para"> This is a paragraph. It is not an interesting paragraph. Sorry about that. </p> <p id="output"></p>
