JavaScript JavaScript and the DOM (Retiring) Traversing the DOM Child Traversal

Changing paragraph text color programmatically

I need to loop through the 'paragraphs' object and, if a child of that object is a paragraph, to change the text color of the paragraph to blue. I'm checking each child to see if it's a paragraph, but I must be missing the appropriate property to set the color to blue. Hoping someone can assist.

app.js 
const section = document.querySelector('section');
let paragraphs = section.children;
for (let i=0; i < paragraphs.length; i++) {
    if (paragraphs[i] === 'p') {

        paragraphs[i].style.background = '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>

Good job on resolving your issue! :+1: But for the benefit of other students reading this question:

  • to identify the type of element, you can examine the tagName property
  • values in tagName will always be upper case
  • the name of the property that sets text color is simply "color" (not "background")
