What exactly do they want here?

My code works and it uses the concepts introduced but still doesn't pass. What exactly are they looking for?

app.js 
const section = document.querySelector('section');
let paragraphs = section.children;
for(let i =0; i < paragraphs.length; i++){
  paragraphs[i].style = "color : blue";
}
section.nextElementSibling.querySelector('p').style.color = "blue";
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>Child Traversal</title>
    </head>
    <body>
        <section>
            <p>This is the first paragraph</p>
            <p>This is a slightly longer, second paragraph</p>
            <p>Shorter, last paragraph</p>
        </section>
        <footer>
            <p>&copy; 2016</p> 
        </footer>
        <script src="app.js"></script>
    </body>
</html>

it's element.style.rule = 'value', not element.style = 'rule : value', so basically adapt what you have in the loop to be like what you have below it.

Thanks that works.

Seems their result testing isn't too robust to different solutions.
