What is the difference between width and innerWidth in jQuery?
Width in jQuery
The width is the horizontal measurement of the container, for example, width of a div. It excludes the padding, border, or margin.

You can try to run the following code to learn how to get the width of an element in jQuery:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
alert("Width of div element: " + $("div").width());
});
});
</script>
</head>
<body>
<div style="height:200px;width:400px;padding:20px;margin:1px;border:1px solid red; background-color:gray;"></div><br>
<button>Get Width of div</button>
</body>
</html>innerWidth in jQuery
The innerWidth() returns the inner width of the first matched element. It includes padding, but not border and margin.

$("button").click(function(){
alert("Inner Width of div element: " + $("div").innerWidth());
});
});
</script>
