Requesting your help to verify my code and create a website with HTML5 and CSS3, trying to click on a menu text to update a "section" with a different web page but at the time it runs the click event does not perform any action; Javascript has been used to try to do it.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<link rel="stylesheet" href="Style.css">
<script type="text/javascript">
$(document).ready(function() {
$("#ejercicio1").click(function() {
$("#contenido").load("new 1.html");
});
});
</script>
