For every paragraph element change the color to be blue.

Hey there- I get the error "task one is no longer working"- however, I copied my code into Codepen and it works just fine.

Thanks!

app.js 
const section = document.querySelector('section');
let paragraphs = section.children;
for(i=0;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>

Try to define let i = 0. You need to introduce the variable before calling it I guess.

const section = document.querySelector('section'); let paragraphs = section.children; for (let i = 0; i < paragraphs.length; i += 1) { paragraphs[i].style.color="blue"; }

i ran this and it worked perfectly

have you tried declaring i as a var or let?
