How can i change the url into a .hlml link ?

This is my .htaccess file :


RewriteEngine on
RewriteRule ^game/([0-9]+)/([_A-Za-z0-9-]+).html file.php?f=$1 [L]
RewriteRule ^category/([0-9]+)/([_A-Za-z0-9-]+)/?$ browse.php?c=$1 [L]
RewriteRule ^category/([0-9]+)/([_A-Za-z0-9-]+)/([0-9]+).html browse.php?c=$1&page=$3 [L]
RewriteRule ^profile/([0-9]+)/([_A-Za-z0-9-]+).html profile.php?u=$1 [L]
RewriteRule ^page/([0-9]+).html page.php?p=$1 [L]




I want all my site urls to be .html at the end.

 

what i meant was to create a Jocuri-cu-Masini.html page empty page in notepad and past the refresh code.

 

Ok but as i said before , i want for seo to rewrite my pages , if i do this it will not be considered black hat seo?
