Simple YouTube Menu Effect with CSS3 & JavaScript

Today we’ll show you how to recreate the little menu effect that you can see in the left side-menu on YouTube when watching a video (where it says “Guide”). The menu is made of a little menu icon, a label and a list of menu items that appears when the label or menu icon is clicked. Once it’s clicked the menu icon slides to the right and the label moves up while the list items fade in sequentially. We’ll add some more style and effects to it in order to make it a bit more interesting.
