Images, css files etc need to reside outside the application folder, preferably in an "assets" folder that is located on the same level. You can then link to them in your views like so:

图像,css文件等需要驻留在应用程序文件夹之外,最好位于同一级别的“assets”文件夹中。然后,您可以在视图中链接到它们,如下所示:

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

Your folder structure would be:

您的文件夹结构将是:

ci-project
-index.php
-application
-assets
--css // --> style.css
--img // --> logo.png

Maybe ?:

<link rel="stylesheet" href="../code/application/style/style.css">
