can some one please give me an advice to pass this loop?

I think what I am doing wrong in this challenge is the loop but I am not so sure! I also tried to come up with a solution for up but my mind did not come up with any thing so any tips from you guys will be appreciated the challenge task is: 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 = 0 ; i < section.length; i =+1) {
    paragraphs.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>

Hi Yousif,

  1. In your "for" statement where you increment the index variable (i), you need to reverse the + and = operators.
  2. In your "for" condition you're currently checking the length of "const section" which = 1 (not 3). So check the length of "paragraphs" instead.
  3. Inside the "for" loop you need to include the index variable ( [i] ) to target each paragraph element. Like this:
 paragraphs[i].style.color = "blue";
