表单提交后缺少CSS文件

我创建了一个发送文本的表单。我用不同的控制器和动作重定向表单提交后的页面。每当我提交表单时，我正在使用的css文件"temp.css"就会丢失，仅用于该特定页面。所以我遇到了一些设计问题。谁能解释一下为什么会这样?

<div  ng-init='textcontents = <?php  echo (!empty($text_info))?json_encode($text_info):'[{"0":"empty"}]'; ?>'> 
    <?php echo $this->Form->create('TwilioText', array('url' => array('controller' =>'Emailer','action' => 'text_sendmsg'),'novalidate')); ?>
    <div class="hidden">
    <?php
        $value = isset($cust_detail['customerid']) ? $cust_detail['customerid'] : '';
        echo $this->Form->input('TwilioSentText.customerid', array('type' => 'text', 'ng-model' => 'livedata.customerid', 'value' => $value));
        echo $this->Form->input('TwilioSentText.firstname', array('type' => 'text', 'ng-model' => 'livedata.firstname', 'value' => $cust_detail['firstname']));
        echo $this->Form->input('TwilioSentText.lastname', array('type' => 'text', 'ng-model' => 'livedata.lastname', 'value' => $cust_detail['lastname']));
        ?>
    </div>
    <div class="textmsg">
        <div class="textleft pull-left">
            <?php foreach ($textChat as $key => $value) {
                    if($value['msg'] == 'in'){ ?>
