StyleSheetList: length property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The length
read-only property of the StyleSheetList
interface returns the number of CSSStyleSheet
objects in the collection.
Value
An integer indicating the number of items in the collection.
Examples
In the following example, length
is printed to the console, and also used in a for loop to print each individual CSSStyleSheet
object to the console.
js
let length = document.styleSheets.length;
console.log(length);
for (let i = 0; i < length; i++) {
console.log(document.styleSheets[i]);
}
