To
implement add css class to div or remove css class from div functionality in JavaScript we need to write
much code but in JQuery we can achieve this
functionality just by simple properties addClass
and removeClass that would be like
as shown below
<script type="text/javascript">
$('#btnAddCSS').click(function() {
$('#samplediv').addClass('sampleCSS')
})
$('#btnRemoveCSS').click(function() {
$('#samplediv').removeClass('sampleCSS')
})
</script>
