将引导程序验证消息颜色更改为红色

Question

如果输入的电子邮件无效，我有一个发布错误消息的表单。我希望将错误消息文本更改为红色。我怎么能这样做？

$('#subscribe-form').bootstrapValidator({
  live: 'disabled',
  fields: {
    email: {
      validators: {
        emailAddress: {
          message: 'Please enter a valid email address'
        }
      }
    },
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form role="form" id="subscribe-form">
  <div class="form-group">
    <input type="email" class="form-control custom-email" name="email" id="email" placeholder="Email Address">
  </div>
  <button type="submit" class="btn btn-large custom-button">Sign up !</button>
</form>

      }
    },
  }
});

如果正确添加了Bootstrap，您应该已将错误文本设置为红色。如果没有，这将解决这个问题。

small.help-block {
   color: #F44336 !important;
}

$('#subscribe-form').bootstrapValidator({
  live: 'disabled',
  fields: {
    email: {
      validators: {
        emailAddress: {
          message: 'Please enter a valid email address'
        }
      }
    },
  }
});

small.help-block {
  color: #F44336 !important;
}

<form role="form" id="subscribe-form">

  <div class="form-group">

  </div>

  <button type="submit" class="btn btn-large custom-button"> Sign up ! </button>
</form>
