Code Injection

Site URL: https://www.dekoninggroup.com/

Hello everyone, 

I bought a plugin from Squarestud.io and i haven't heard back from their support team for almost a week.

The plugin is a logo loading screen using the site's logo.  I was hoping increase the logo size of the logo showing on the load screen. Any help is appreciated!

Here is the code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<div class="logoload"></div>
<script>
$(function() {
  var loadLogo = $('header').find('img').attr('src');
  $('.logoload').css('background-image', 'url(' + loadLogo + ')');
});
</script>
<style>
.logoload {
  /* SET BACKGROUND COLOR */
  background-color: #00000;
  /* SET BACKGROUND SIZE */
  background-size: 90px;
  position: fixed;
  left: 0px;
  top: 0px;
  width: 100%;
  height: 100%;
  z-index: 9999;
  background-position: center;
  background-repeat: no-repeat;
}
</style>
<script type="text/javascript">
$(window).load(function() {
    $(".logoload").delay(500).fadeOut("slow");
})
</script>
