Hi,
What am I doing wrong in my code?
var section = document.querySelector('section');
var paragraphs = section.children;
for(i = 0; i < paragraphs.length; i = i + 1) {
paragraphs[i].color = blue;
}
<!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>© 2019</p>
</footer>
<script src="app.js"></script>
</body>
</html>

You are very close, there are just a couple of things that need changing slightly:
- Make sure you reference the variable
i
, inside the for loop.for (var i = 0 ...
- to change the color of an element, you need to access this through the style object.
element.style.color
- make sure the style is put into quotation marks, otherwise it is trying to find a variable called
blue
and not the color which is what we want.'blue'
var section = document.querySelector('section');
var paragraphs = section.children;
for(var i = 0; i < paragraphs.length; i = i + 1) {
paragraphs[i].style.color = 'blue';
}
Hope this helps!
