I have googled and tried many solutions which worked for others but not in my case. I don't know why.
Background:
I am learning to use CodeIgniter 2.2.0. I have set up project structure and all the things as below, but still I am not able to load my CSS and JS.
View Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1">
<title> </title>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<!-- solution 1 I have tried: -->
<!-- in below line I tried by using constant set in constants.php file under application/config/ folder -->
<link rel="stylesheet" href="<?php echo (CSS.'dialog.css' );?>" type="text/css">
<!-- solution 2 I have tried: -->
<!-- As my css n script files are under CodeIgniter_2.2.0/assets/css and CodeIgniter_2.2.0/assets/scripts folder respectively -->
<link rel="stylesheet" href="/assets/css/dialog.css" type="text/css">
<!-- solution 3 I have tried -->
<!-- This I tried by using autoload.php settings where I am setting autoload['helper'] = array('url'); -->
<?php echo link_tag('assets/css/dailog.css');?> </br>
<script src="../../script/Plugins/jquery.js" type="text/javascript"></script>
</head>
</html>
Config:
Also I have set
$config['base_url'] = "http://localhost/"; in application/config/config.php file.
Project Folder Structure:
My project folder structure is as follows :

(Application , System, Assets folders are at same level)
The contents of .htaccess file are :
(.htaccess file path : C:\xampp\htdocs.htaccess )
RewriteEngine on
RewriteCond $1 !^(index\.php|images|js|css|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
there are 2 more .htaccess file at C:\xampp\htdocs\CodeIgniter_2.2.0\System and C:\xampp\htdocs\CodeIgniter_2.2.0\application folder
both have single line written :
Deny from all
Also, at C:\xampp\htdocs\, there is a file index.php which is same as the index.php file placed at
C:\xampp\htdocs\CodeIgniter_2.2.0\ in which I have set following things
$system_path = 'CodeIgniter_2.2.0/system';
$application_folder = 'CodeIgniter_2.2.0/application';
Is there anything that I am missing in this? I am not able to load any CSS or JS files on my page.
dialogand then the other two instances aredailog? Is this supposed to be the same file, or do you have multiple CSS files here?
