如何使用codeigniter在css文件中设置base_url（），以访问css文件中的background_image_url？

Question

I'm using codeigniter, I loaded all css files and those are working very well. My directory structure is displayed in following image:

I loaded style.cssusing this code :

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

all style attributes are set very well and working. But after that I found images which are set inside css file are not displaying on my site! My code in css :

.social_nav li.facebook a{ background-image:url("images/socials.png"); background-position:0 -30px; background-size:270px 60px}

So is their any procedure to set base_url() for background-image:url("images/socials.png"
