Why doesn't this work?

Read the JavaScript comments for this code. https://code.sololearn.com/WoOBKjaivtfE/?ref=app

Daniel Cooper You should know that OutTwo returns an array of all elements with class "myOutTwo". Since it's an array, you can't just set a color for it, because Javascript won't know which particular element to apply the style to. If you wanted to set the general color for ALL the elements, you should used a for loop, to loop through the entire array
