title: How to make a floating menu appear after you scroll past a certain point?
body: <p>I want to make four menu tabs appear after you scroll past a certain point (ex: 1000px) on the page. I want them to slide in from left to right when they appear. This is what I'm going for, but on the left side of the browser. Any input is appreciated. </p>
