where do I get this wrong?

it seems right to me

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

for(i=0; i<=paragraphs.length; i+=1){
  paragraphs[i].style.backgroundColor="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; 2019</p> 
        </footer>
        <script src="app.js"></script>
    </body>
</html>

Francesco Paolini Very close, but the assignment was asking for you to change the color of the paragraphs, not the background color. Common mistake that I make all the time myself. So your solution would be:

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

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