it keeps saying "section 1 is no longer passing" but nothing has changed. i'm not sure what i'm doing wrong here.

app.js 
const section = document.querySelector('section');
const 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>

Hey Brian,

Just a general tip - if you're unexpectedly getting a "section 1 is no longer passing", it's usually because you've introduced a compiler error. This will prevent the challenge from running the code at all, which makes section 1 fail... but it's really got nothing to do with the solution you wrote for section 1. Make sense? It's a red herring.

In this case, the compiler error is a RefrenceError - you can't just set i=0 like that, because the challenge environment has strict mode turned on. Just add a let before you set i and you'll be all set.

Cheers :beers:
