Bước 2: Thêm HTML dưới thẻ <body>
<div class="preloader">
<div class="wrapLoading">
<div class="cssload-loader">
<div class="cssload-inner cssload-one"></div>
<div class="cssload-inner cssload-two"></div>
<div class="cssload-inner cssload-three"></div>
</div>
</div>
</div>
Bước 3: Thêm JavaScript trước thẻ đóng </body>
<script>$(window).bind("load", function() {$('.preloader').delay(1000).fadeOut(500);})</script>
<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js'></script>
