Preloader

Preloader is the what you see on some sites before the main content of the web page is loaded.

                
                  <!-- preloader -->
                  <div class="preloader loaded-success fixed inset-0 z-50 bg-gray-100 dark:bg-gray-900">
                    <div class="absolute left-1/2 top-1/2 transform -translate-y-1/2">
                      <div class="relative mx-auto my-12">
                        <div class="inline-block">
