In the box’s exercise, I don’t understand why doesn’t exist the selector for the class=“box”. When it was used it in the \<div **class=“box”** \> either in style.css nor normalize.css

Sorry, I was wrong about the question, because I didn’t see the .box selector in the style.css file, but it is there.
