         html, body {

         color: #636b6f;
         font-family: 'Nunito', sans-serif;
         font-weight: 200;

         }
      </style>
   </head>
   <body>
      <div class="container mt-5">
         <div class="row justify-content-center">
            <div class="col-md-8">
               <div class="card">
                  <div class="card-header">
                     <h2>Laravel 8 Livewire Load More Data on Page Scroll Example</h2>
                  </div>
                  <div class="card-body">
                     @if (session()->has('message'))
                     <div class="alert alert-success">
                        {{ session('message') }}
                     </div>
                     @endif
                     @livewire('load-more-user-list')
                  </div>
               </div>
            </div>
         </div>
      </div>
      @livewireScripts
      <script type="text/javascript">
         window.onscroll = function(ev) {
         if ((window.innerHeight + window.scrollY) >= document.body.offsetHeight) {
         window.livewire.emit('load-more');
         }
         };
      </script>
   </body>
