    paragraphs.style.color ='blue';
}

<!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>

Only a couple of small things, the end code should look like that below:

const section = document.querySelector('section');
let paragraphs = section.children;

for (let i = 0; i < paragraphs.length; i += 1) {
    paragraphs[i].style.color ='blue';
}

In the for loop, I added the "i" to be incremented each time. This is then used in the paragraphs collection, paragraph[i] to update the style in each collection:

paragraphs[0] paragraphs[1] paragraphs[2] etc...

Hope this helps
