php - How do I load css files with a view in CodeIgniter?

Question

I am currently trying to load a css file into a CodeIgniter view in the follow manner:

<link rel="stylesheet" href="<?php echo base_url(); ?>css/style.css">

A blank page is loaded. It seems that when I call the base_url function in the view the page doesn't load because the same thing happens when I call base_url() else where in the view but the page actually loads without css when I remove the calls to that function. Is there something that I need to require in order for the page to load?
