add trailing slash after removing .html extention

Question

My website is non www ,it has wordpress in subdirectory and some static webpages in the root and other subdirectory

1. i want to remove .html extention from the webpages in the root and the others static webpages in subdirectory.
2. add slash at the end.
3. 301 redirect from non slash to url with slash.

so it should be

/articles.html to /articles/

and

/subdirectory/book.html to /subdirectory/book/

the below code

1. working with non slash at the end
2. redirect 301 url with slash to non

here's my .htaccess

 <IfModule mod_rewrite.c>     
 Options +FollowSymLinks -MultiViews


RewriteEngine On     
RewriteBase /

#removing trailing slash
RewriteCond %{REQUEST_FILENAME} !-d    
RewriteRule ^(.*)/$ $1 [R=301,L]

#www to non
RewriteCond %{HTTP_HOST} ^www\.(([a-z0-9_]+\.)?domain\.com)$ [NC]
RewriteRule .? http://%1%{REQUEST_URI} [R=301,L]

#html
RewriteCond %{REQUEST_FILENAME} !-f     
RewriteCond %{REQUEST_FILENAME} !-d    
RewriteRule ^([^\.]+)$ $1.html [NC,L]

#index redirect 
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.html\ HTTP/     
RewriteRule ^index\.html$ http://domain.com/ [R=301,L]
RewriteCond %{THE_REQUEST} \.html     
RewriteRule ^(.*)\.html$ /$1 [R=301,L] 
</IfModule>

PS everything is ok with the wordpress , the problems with static pages only.

Thanks in advanced

I seem not to be able to comment, it seems, but i am guessing wordpress has a separate .htaccess file that contains extra rules in order to make those pages work. I would guess your static pages will need extra explicit rules these can be added to the .htaccess or in the virtualhost but in both cases should look like: RewriteCond %{SCRIPT_FILENAME} !-d RewriteCond %{SCRIPT_FILENAME} !-f RewriteRule ^staticpage1$ ./staticpage1.html RewriteRule ^staticpage2$ ./staticpage2.html
