php - 如何在 php form_submit 按钮中添加样式或放置类

Question

我只是想让我的按钮看起来很棒，但我不知道如何应用样式或将类放在这样的按钮上 http://i.stack.imgur.com/EFvzg.jpg

<?php echo form_submit('submit', 'Submit');?>

我想把这个 css 属性放到我的按钮上，让它看起来像这样 http://i.stack.imgur.com/JmFLI.jpg ..

.btnBack{
      background: #3498db;
      border: solid 1px;
      border-color: #3498db;
      background-image: -webkit-linear-gradient(top, #3498db, #2980b9);
      background-image: -moz-linear-gradient(top, #3498db, #2980b9);
      background-image: -ms-linear-gradient(top, #3498db, #2980b9);
      background-image: -o-linear-gradient(top, #3498db, #2980b9);
      background-image: linear-gradient(to bottom, #3498db, #2980b9);
      -webkit-border-radius: 5;
      -moz-border-radius: 5;
      border-radius: 5px;
      color: #ffffff;
      font-size: 15px;
      padding: 5px;
      width: 100px;
      text-decoration: none;
    vertical-align: middle;
    }

请教我怎么做..谢谢

如果这是代码点火器:

form_submit('submit', 'Submit',"class='btnBack'");
