CSS :scope pseudo-class

Last Updated : 30 Aug, 2022

A scope element forms a context for a block of styles. That element provides a reference point for selectors to be matched against. A scope element is defined using the scoped attribute. Styles declared with scoped attributes will be applied to all elements inside its parent element.

Syntax:

:scope

Example 1:

HTML

<!DOCTYPE html>
<html>
<title>GeeksforGeeks</title>
<body>
    <h1 style="text-align: center; 
            color: green;" id="paragra">
        Welcome to GeeksforGeeks.
        It's a Computer Science portal.
    </h1>
    <p style="color: #000; text-align: center;" id="opt">
    </p>

    <script>
        let para =
            document.getElementById("paragra");
        let opt =
            document.getElementById("opt");
        if (para.matches(":scope")) {
            opt.innerText =
                "Yeah!!, we are under scope GeeksforGeeks";
        } 
    </script>
</body>
</html>
