Yii2 如何将图标移动到中心

我有导航栏，代码如下

 <?php
        NavBar::begin(['brandLabel' => '',
                    'options' => [  //'class' => 'navbar-inverse navbar-fixed-top',
                                    'style' => 'height: 30px; margin-top:-10px;',]
                                ]);
        echo Nav::widget([
                    'items' => [['label' => 'Home', 'url' => ['/site/index']],
                                ['label' => 'About', 'url' => ['/site/about']],],
                    'options' => ['class' => 'navbar-nav','style' => 'align:center',],
                                ]);
        NavBar::end();
        ?>

是否可以将中堂图标移到中心？。。

引导导航栏左侧，导航栏右侧正常工作。

这一个应该可以工作，最好将内联css移动到某个类

NavBar::begin(['brandLabel' => '',
                'options' => [  //'class' => 'navbar-inverse navbar-fixed-top',
                                'style' => 'height: 30px; margin-top:-10px;',]
                            ]);
    echo Nav::widget([
                'items' => [['label' => 'Home', 'url' => ['/site/index']],
                            ['label' => 'About', 'url' => ['/site/about']],],
                'options' => ['class' => 'navbar-nav','style' => 'display: flex;justify-content: center;float: none;',],
                            ]);
    NavBar::end();

您可以在菜单中添加自己的ID

<?php
NavBar::begin(['brandLabel' => '',
        'options' => [
            'class' => 'navbar navbar-fixed-top clients',
            'id' => 'my-menu',
        ],
]);
echo Nav::widget([
    'items' => [['label' => 'Home', 'url' => ['/site/index']],
        ['label' => 'About', 'url' => ['/site/about']],],
    'options' => ['class' => 'navbar-nav', 'style' => 'align:center',],
]);
NavBar::end();
?>

div#my-menu-collapse ul li {
    text-align: center;
    margin: 0 auto;
}
