How to direct the direct access to the site resources using htaccess? but should work in normal load

RewriteEngine on

RewriteCond %{HTTP_REFERER} !^$ [NC] 
RewriteCond %{HTTP_REFERER} !^http://ift.tt/1g9d2Sy [NC] 
RewriteRule \.(jpeg|png|css|js)$ - [NC,F]

Here it blocks, but in normal loading the files are not able to load, only html contents are loaded, resources not appearing in page. Like images,css, js etc.
