dynamic_sidebar / register_sidebarについて

。
WordPressでのウィジェットのカスタマイズについて質問です。
下記の2つめのコードが最終的に吐き出したいhtmlです。
dynamic_sidebar()関数を使ってコードを吐き出す場合には、どのように個々のウィジェットに対してhtmlを適応できるのでしょうか？
駄文で申し訳ありません。

よろしくお願いします。

register_sidebar(array(
        'name' => __('Test', 'admin'),
        'description' => __('Top of Services area'),
        'id' => 'services',
        'before_widget' => '<div class="row section featured topspace">',
        'after_widget' => '</div>',
        'before_title' => '<h2 class="section-title"><span>Services</span>',
        'after_title' => '</h2>'
    ));

<div class="row section featured topspace">
                            <h2 class="section-title"><span>Services</span></h2>
                            <div class="row">
