you have included javascript file two time first in the header and second at the last inside body tag. first remove one of them and there is a spelling mistake in backgroundColor as you can see here element = document.querySelector("#header").style.backgroundColor = 'green';

but the error still there. and i am jest getting the value from html document. – shine Mar 17 '22 at 06:29
the reason is in the `element` variable you have assign value only. If you want to assign an element inside the variable the code will be `element = document.querySelector("#header");` than only you can get actual element inside your variable. – haither azeez Mar 17 '22 at 06:46
After assign the element inside the variable you can add style. first `element = document.querySelector("#header");` than second `element.style.backgroundColor = 'green';` – haither azeez Mar 17 '22 at 06:48
var element; element = document.querySelector("#header"); var e2=element.style.backgroudColor; console.log(e2); – shine Mar 17 '22 at 08:45

you can use document.getElementById('header').style.backgroudColor like this.
