I change my .htaccess to what you gave me, there is no .htaccess in the news folder - only in my /public_html folder. It has change a little bit but it's not loading the style sheet now and displaying the news/comments twice.
The link to my stylesheet was 'css/style.css' so I changed it to '/css/style.css' and it worked properly. And the reason why it was displaying it twice was because I had included it twice haha. My bad.
