hi everybody

how can I add a preloader on my forum?

Preloader in the form of an animated svg icon

1. Create the HTML markup for the preloader and place it immediately after the opening body tag:

<div class="preloader">
  <svg class="preloader__image" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">
    <path fill="currentColor"
      d="M304 48c0 26.51-21.49 48-48 48s-48-21.49-48-48 21.49-48 48-48 48 21.49 48 48zm-48 368c-26.51 0-48 21.49-48 48s21.49 48 48 48 48-21.49 48-48-21.49-48-48-48zm208-208c-26.51 0-48 21.49-48 48s21.49 48 48 48 48-21.49 48-48-21.49-48-48-48zM96 256c0-26.51-21.49-48-48-48S0 229.49 0 256s21.49 48 48 48 48-21.49 48-48zm12.922 99.078c-26.51 0-48 21.49-48 48s21.49 48 48 48 48-21.49 48-48c0-26.509-21.491-48-48-48zm294.156 0c-26.51 0-48 21.49-48 48s21.49 48 48 48 48-21.49 48-48c0-26.509-21.49-48-48-48zM108.922 60.922c-26.51 0-48 21.49-48 48s21.49 48 48 48 48-21.49 48-48-21.491-48-48-48z">
    </path>
  </svg>
</div>

Any other image can be used as svg.

2. Add Custom.css:

.preloader {
  position: fixed;
  left: 0;
  top: 0;
  right: 0;
  bottom: 0;
  overflow: hidden;
  /* background color */
  background: #e0e0e0;
  z-index: 1001;
}
.preloader__image {
  position: relative;
  top: 50%;
  left: 50%;
  width: 70px;
  height: 70px;
  margin-top: -35px;
  margin-left: -35px;
  text-align: center;
  animation: preloader-rotate 2s infinite linear;
}
@keyframes preloader-rotate {
  100% {
    transform: rotate(360deg);
  }
}
.loaded_hiding .preloader {
  transition: 0.3s opacity;
  opacity: 0;
}
.loaded .preloader {
  display: none;
}

3. Let's put the following script in the globalTemplate before </body>:

<script>
  window.onload = function () {
    document.body.classList.add('loaded_hiding');
    window.setTimeout(function () {
      document.body.classList.add('loaded');
      document.body.classList.remove('loaded_hiding');
    }, 500);
  }
</script>
