Challenge Task 2 of 2 For every paragraph element change the color to be blue.

(Hint: remember, paragraphs contains a collection of elements, so you'll need to use a loop and access each element inside.)

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

for(let i=O; i<paragraphs.length; i+=1){
 paragraphs[i].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>

You accidentally set your i variable to a capital O instead of a zero:

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

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