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.


const section = document.querySelector('section');
let paragraphs = section.children;
<!DOCTYPE html>
        <title>Child Traversal</title>
            <p>This is the first paragraph</p>
            <p>This is a slightly longer, second paragraph</p>
            <p>Shorter, last paragraph</p>
            <p>&copy; 2016</p> 
        <script src="app.js"></script>

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?
