Spinner loading - stays centered on screen even when scrolling up or down

<div id="Dvloading" style="float: left;">
        <i id="loadingSpinner" class="icon-spinner icon-spin blue" style="margin-left: 50%; position:absolute ; margin-top: 25%; z-index: 1000; font-size: 800%;"></i>
</div>

This code displays a loading spinner while the page is loading, positioned above a grid view. However, when scrolling through a large number of rows in the grid, the loading graphic moves with the page. How can I keep it centered on the screen at all times, even when scrolling?

I would greatly appreciate any assistance with this issue.

Answer №1

After going through my previous responses, I decided to update with a more contemporary approach. In the new solution, specifying height or width is no longer necessary. This updated method provides a more versatile and generic solution.

.center {
   position: fixed;
   top: 50%;
   left: 50%;
   transform: translate(-50%, -50%);
}

Give this a try:

.centered {
  position: fixed;
  top: 50%;
  left: 50%;
  margin-top: -50px; //Half of the height of the loading graphic
  margin-left: -50px; //Half of the width of the loading graphic
}

Below is the solution I came up with:

    .k-loading-image{

    }
    
    .longDiv {

  <div class="longDiv">This is a long DIV...</div>
  
  <script>
    const showBusyIndicator = (show) => kendo.ui.progress($("body"), show);
    $(document).ready(showBusyIndicator(true));
