Next, change the color of each child paragraph to blue.
(Remember: paragraphs is a collection of elements, so you'll first need to use a loop to access each element in the collection.)

var section = document.querySelector('section');
var paragraphs = section.children;
if (paragraphs.children) {
paragraphs.style.color = 'blue';

var paragraphs = section.children;
for (var i = 0; i < paragraphs.length; i += 1) {
paragraphs[i].style.color = "blue";
}
You need to loop through the paragraphs meaning all the children of the section element and then only assign the blue color. This should work. Hope this helps)))

Courses Plus Student 23,765 PointsHi, Alexandra, the [i] in paragraph provides the index for the paragraph to modify the color, so [0] would modify the first pararaph, while the [i] woudl go (loop) through all the paragraphs and provide them with the color property

Front End Web Development Techdegree Student 9,313 PointsI got stuck on this challenge.
Initially, I wrote,
for (var i = 0; i < paragraphs.length; i += 1) { paragraphs[i].style.color = "blue"; }Why did you include [i]? I thought it implicitly JS knows to loop through all paragraph elements.
