<head>
    <meta charset="utf-8">
    <title>outerWidth demo</title>
    <style>
        p {
            margin: 10px;
            padding: 5px;
            border: 2px solid #666;
        }
    </style>
    <script src="https://code.jquery.com/jquery-3.4.1.js"></script>
</head>

<body>

    <p>Hello</p>
    <p></p>

    <script>
        var p = $("p").first();
        $("p").last().text(
            "outerWidth:" + p.outerWidth() +
            " , outerWidth( true ):" + p.outerWidth(true));

        }
