base_url() and css -img-js

[eluser]Ngulo[/eluser]
hi all,i've read we must always use base_url() before all img tags or css's links or js's links is it true?

i would like to use this method but...

i'm having serious problem loading css and js sheets

i've put my css and js folders on the same level of index.php and system folder

i'm using links like this:

Code:

<link rel="stylesheet" href="../css/template.css" type="text/css" media="screen">

and all works in application folder ,

but for example:

if i load www.asd.it the css and js's takes away

instead
if i load www.asd.it/index/Home they are showed

i haven't take away with .htaccess the index.php i'm working on the basics ,without changing $config's data(changed only the main features like base_url() and default controller ....
