如何在Bootstrap Contact表单中更改成功消息字体大小？

Question

在http://ahepa215.org/contact.html我正在使用我为Bootstrap看到的响应式联系表单。当您提交它时，会从contact.php页面向您提供成功消息。     $okMessage = 'Contact form successfully submitted. Thank you, I will get back to you soon!';如何让这条信息更大？

<form id="contact-form" method="post" action="contact.php" role="form">
<div class="messages"></div>
<div class="controls">
<div class="row">
                                <div class="col-md-6">

这是整个PHP代码，我无法看到如何将其添加到代码段框中;

你可以用这样的css处理它。

.messages .alert-success {
    font-size: 30px;

}
