Geting z-index With DOM style.zIndex

I was not able to get the z-index of my page element using document.getElementById(“id”).style.zIndex. Please see my code in codepen


AFAIK, the property only gives you access to CSS properties defined inline. You should get the element’s computed style, like so:

var el = document.getElementById('block' + randIndex)
var style = window.getComputedStyle(el)
var zI = style.zIndex;

Then things will work as expected.

i m also looking for solution for same code so thank u so much becoz i found my solution. Thanks again
