I have tried by this script
<script>
(function ($) {
"use strict";
// Spinner
var spinner = function () {
setTimeout(function () {
if ($('#spinner').length > 0) {
$('#spinner').removeClass('show');
}
}, 1);
};
spinner();
</script>
and html code
<!-- Spinner Start -->
<div id="spinner" class="show bg-white position-fixed translate-middle w-100 vh-100 top-50 start-50 d-flex align-items-center justify-content-center">
<div class="spinner-border text-primary" style="width: 3rem; height: 3rem;" role="status">
<span class="sr-only">Loading...</span>
</div>
</div>
<!-- Spinner End -->
It's hard to judge your problem without seeing the CSS in question. My suspicion is that removing show isn't enough to hide the element unless you have another class applying some kind of hide class. See the simplified example:
// Spinner
var spinner = function () {
setTimeout(function () {
if ($('#spinner').length > 0) {
$('#spinner').removeClass('show').addClass('hide')
}
}, 2000);
}
spinner();.container {
background: white;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
position: relative;
}
.spinner {
position: absolute;
top: 50%;
left: 50%;
background: blue;
transform: translate(-50%, -50%);
padding: 1em;
color: white;
}
.show {
display: block;
}
.hide {
display: none;
