Example 1:

  <! DOCTYPE html>  <html>  <head>  <title>  Load more bootstrap Example  </title>  <meta name=”viewport” content=”width=device-width, initial-scale=1″>  <style>  * {    margin: 0;    padding: 0;  }  body {    margin: 0;    padding: 0;  }  .flex {    display: flex;    flex-wrap: wrap;    justify-content: center;    align-items: center;  }  h2 {    font-weight: bold;    margin-bottom: 2.5rem;    color: #aaa;    align: center;    font-size: 30px;    margin-top: 1.5rem;    font-weight: 1000;  }  p {  font-weight: bold;    margin-bottom: 2.5rem;    color: #aaa;    align: center;    font-size: 20px;    margin-top: 1.5rem;    font-weight: 1000;  }  h3 {    font-weight: bold;    margin-bottom: 2.5rem;    color: #aaa;    align: center;    font-size: 30px;    margin-top: 1.5rem;    font-weight: 1000;  }  body {    background: #191828;   color: #aaa;    font-family: “Roboto”, Arial, Helvetica, sans-serif;    font-size: 16px;    font-weight: 300;    letter-spacing: 0.01em;    line-height: 1.6em;    margin-top: 30;  }    .content {    height: 100px;    width: 45%;    color: #fff;    font-size: 24px;    line-height: 100px; /* centering text just for view */    text-align: center;    background-color: grey;    margin: 5px;    border: 1px solid lightgrey;    display: none;  }  #loadMore {    width: 200px;    color: #fff;    display: block;    text-align: center;    margin: 20px auto;    padding: 10px;    border-radius: 10px;    border: 1px solid transparent;    background-color: blue;    transition: .3s;  }  #loadMore:hover {    color: blue;    background-color: #fff;    border: 1px solid blue;    text-decoration: none;  }  .noContent {    color: #000 !important;    background-color: transparent !important;    pointer-events: none;  }  a:active {  text-decoration: none;  }  a {  color: #aaa;  text-decoration: none;  font-size: 2rem;  }  a:visited {  text-decoration: none;  }  #loadMore {    text-align: center;    font-size: 1.5em;    color: #fff;    letter-spacing: -5px;    font-weight: 700;    text-transform: uppercase;    animation: blur .75s ease-out ;    text-shadow: 0px 0px 5px #fff, 0px 0px 7px #fff;  }  .content {    text-align: center;    font-size: 1.5em;    color: #fff;    letter-spacing: 2px;    font-weight: 700;    text-transform: uppercase;    animation: blur .7s ease-out ;    text-shadow: 0px 0px 5px #fff, 0px 0px 7px #fff;  }  em {    font-family: Georgia, serif;    line-height: 1.6;  }  @keyframes blur {    from {      text-shadow:0px 0px 10px #fff,        0px 0px 10px #fff,         0px 0px 25px #fff,        0px 0px 25px #fff,        0px 0px 25px #fff,        0px 0px 25px #fff,        0px 0px 25px #fff,        0px 0px 25px #fff,        0px 0px 50px #fff,        0px 0px 50px #fff,        0px 0px 50px #7B96B8,        0px 0px 150px #7B96B8,        0px 10px 100px #7B96B8,        0px 10px 100px #7B96B8,        0px 10px 100px #7B96B8,        0px 10px 100px #7B96B8,        0px -10px 100px #7B96B8,        0px -10px 100px #7B96B8;    }  }  </style>  </head>  <body>  <h3 align=”center”> <em> Example </em> </h3>      <h2 align=”center”> <em> Load more Content using bootstrap Example </em> </h2>    <br /> <br />    <div class=”container”>    <div class=”flex”>  <div class=”content”> <a href=”#”> Content 1 </a> </div>      <div class=”content”> <a href=”#”> Content 2 </a> </div>      <div class=”content”> <a href=”#”> Content 3 </a> </div>      <div class=”content”> <a href=”#”> Content 4 </a> </div>      <div class=”content”> <a href=”#”> Content 5 </a> </div>      <div class=”content”> <a href=”#”> Content 6 </a> </div>      <div class=”content”> <a href=”#”> Content 7 </a> </div>      <div class=”content”> <a href=”#”> Content 8 </a> </div>      <div class=”content”> <a href=”#”> Content 9 </a> </div>      <div class=”content”> <a href=”#”> Content 10 </a> </div>      <div class=”content”> <a href=”#”> Content 11 </a> </div>      <div class=”content”> <a href=”#”> Content 12 </a> </div>      <div class=”content”> <a href=”#”> Content 13 </a> </div>      <div class=”content”> <a href=”#”> Content 14 </a> </div>      <div class=”content”> <a href=”#”> Content 15 </a> </div>      <div class=”content”> <a href=”#”> Content 16 </a> </div>    </div>     <a href=”#” id = “loadMore”> Load More </a>  </div>  <script src =”https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js”> </script>  <script src =”https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js”> </script>  <script>  $(document).ready (function () {    $(“.content”).slice(0, 4).show();    $(“#loadMore”).on(“click”, function(e){      e.preventDefault();      $(“.content:hidden”).slice(0, 4).slideDown();      if ($(“.content:hidden”).length == 0) {        $(“#loadMore”).text(“No Content”).addClass(“noContent”);      }    });    })  </script>  </body>  </html>
