Relative path how to
===

So right now when I am linking to any file I have to specify the absolute path looking like this
    
    <link rel="stylesheet" type="text/css" 
    href=  "F:/XmppOld/XAMPP2/htdocs/MAIN_SITE_LAYOUT/css/stylemainpage.css"
 
    I would like to narrow it down to 
    href="/css/stylemainpage.css

Im not sure how to. I tried placing the stylemainpage.css inside the page being viewed, but it didnt work. So i am wondering
