A help using styles

Question

I want to change the color of all header's child tag by using JS and deleting the text-decoration from all links from a ul by using JS too... Any one can tell me how I can do it? I don't want to use css directly(I could, but not)...

Answer 1

U can use document.querySelectorAll() for CSS selector
example : selecting all child inside div
div > *

for header :

var header = document.querySelectorAll("header")
console.log(header)
header.forEach(header =>{
header.style.color = "green "
})
//}

Do same with anchor
