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 on which the method was called.
Syntax
:scope
Examples
Identity match
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>
Result
Direct children
A situation where the :scope
pseudo-class prove to be useful is when you need to get direct descendant of an already retrieved Element
.
JavaScript
var context = document.getElementById('context'); var selected = context.querySelectorAll(':scope > div'); document.getElementById('results').innerHTML = Array.prototype.map.call(selected, function (element) { return '#' + element.getAttribute('id'); }).join(', ');
HTML
<div id="context"> <div id="element-1"> <div id="element-1.1"></div> <div id="element-1.2"></div> </div> <div id="element-2"> <div id="element-2.1"></div> </div> </div> <p> Selected elements ids : <span id="results"></span> </p>
