I have this code
<link href = "<?php echo base_url(); ?>css/style.css” rel=”stylesheet" type="text/css" />
which supposed to load the style.css from the css folder. The echo base_url() itself works.
I also have autoloaded the url helper, so i really don't see the problem here, but it still doesn't load.
Also make sure that the directory is not "blocked" by the .htaccess file, if you are using it to remove index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|css|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
Personally I would move the css diectory into an assets directory:
/assets/css
/assets/js
/assets/img
the default location for css files is the same level as the application i.e.,
/css
/application
Check the path as has been suggested.
View the source of the page and click the css file link, if it 404s then check your .htaccess file and make sure that that directory is available!
try including the relative link in the function like on the user_guide
< link href = " < ? php echo base_url('css/style.css') ; ? >” rel=”stylesheet" type="text/css"/>
application/views/globals/css/style.css" type="text/css" media="screen" />
or whatever your folders srtucture is!
