Question

我的头已经结了。我试图将附加的标题和段落居中，但无论我做什么，它都会向左拉。有什么想法吗？这是代码（PS - 我是初学者:)）

<!DOCTYPE html>

        <head>

                <style type="text/css">

                    #appSummary {

                        text-align:center;

                    }

                </style>

        </head>

        <body>

            <div class="container">

                <div class="row" id="appSummary">

                    <h1>This is a H1 Header</h1>
                    <p>Paragraph with text. Paragraph with text. Paragraph with text.</p>
