One Thing Per Page Design using HTML, CSS, JavaScript and JQuery

Welcome to yet another interesting tutorial in which we will be designing a webpage. The webpage shows a single item in a single view and when scrolled jumps to another item.

Source Code

<script type="text/javascript" src="jquery.min.js"></script>
<link rel="stylesheet" href="bootstrap.min.css">


<style type="text/css">

  .slide{

    margin-bottom: 10px;
