css, js, img in view don't work

I have this structure but can't acces (css, js, img) files

Code:

<?php echo base_url('application/views/admin/css/style.css'); //don't work ?>
<?php echo base_url('application/views/default/css/style.css'); //don't work ?>

application
 - views
  -- template
   --- admin
    ---- css
     ----- style.css
    ---- js
    ---- img
  --- default
   ---- css
    ----- style.css
   ---- js
   ---- img

i have this .htaccess

RewriteEngine On
#RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php/$1 [L]

Now i remove htaccess from application but is not a good solution
