Hello Alexandru,

The next step in the challenge is to change the color of each child paragraph to blue, keeping in mind "paragraphs" is a collection of elements, so you'll first need to use a loop to access each element in the collection.

So you need to use a "for" loop to loop through each paragraph element and assign it the CSS color property of "blue".

var section = document.querySelector('section');
var paragraphs = section.children;

for(let i = 0; i < paragraphs.length; i++) {
  paragraphs[i].style.color = "blue";
}

Hope this helps get you through the challenge!

Heidi
