:scope

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.

Syntax

:scope

Example

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.

JavaScript

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!";
}

HTML

<p id="para">
  This is a paragraph. It is not an interesting paragraph. Sorry about that.
</p>
<p id="output"></p>
