如何在"Combinator“css压缩插件中使用单个css文件？

Question

嗨，我正在使用"Combinator“，它是一个用于压缩js和css的插件。Combinator link and steps

根据他们所说的文档，在视图或布局中添加以下行

<?php $combinator->add_libs('js', array('jquery'));?> 
<?php $combinator->add_libs('css', array('styles'));?> 

但是如何添加单个css文件而不是整个css呢？

帮助器类代码：

    <?php  
class CombinatorHelper extends Helper { 
    var $Vue = null; 
    var $libs = array('js' => array(), 'css' => array());

    var $cachePath = null;

你试过这个吗？

<?php $combinator->add_libs('js', array('jquery', 'other_lib', 'third_lib'));?> 

顺便说一句，如果你现在正在你的应用程序中实现组合器插件，我建议你使用Mark Story的AssetCompress Plugin，它更新，文档也更好。
