can an html element have a class and id code example
Example: html script id and class
<!--
The script tag's id and class property work just like in any html tag.
Possible use case is to add css styles to your script tag.
Using e.g. 'class="createFunctionality" type="text/javascript"' in a
script is a good practice if you use a editor,
that displays the name of the script when collapsed,
as part of documentation; e.g. Indicate what the script does.
You can also view the source code of the script like this:
-->
<!-- Rememer to add jquery! -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script class="foo" type="text/javascript">
function foobar() {
var a = 1;
}
</script>
<div id="showScript">Show me the script.</div>
<script type="text/javascript">
$('#showScript').click(function(event) {
event.preventDefault();
$("<div>").html($(".foo").text()).appendTo($("body"));
});
</script>
