CSSStyleDeclaration: item() method
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 CSSStyleDeclaration.item()
method interface returns a CSS property name from a CSSStyleDeclaration
by index.
This method doesn't throw exceptions as long as you provide
arguments; the empty string is returned if the index is out of range and a
TypeError is thrown if no argument is provided.

js
const style = document.getElementById("div1").style;
const propertyName = style.item(1); // or style[1] - returns the second style listed
