CNC and mod_rewrite?

Question

htaccess

Greetings.
I googled and decided to go here. There is a link like this: domain/profile.php?param1=value1¶m2=value2
You need to make a CNC like this: domain/value1/value2
I did this using a generator:

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)$ /profile.php?param1=$1&param2=$2 [L]

I click on the link of the first type, the link is not converted to the second type. I suspect that in htaccess it is also necessary to make a redirect rule to a link of the second type. If true, how to implement it?
And the second. When I manually type in the link domain/value1/value2 into the browser line , the page loads, but without styles. What could be the problem here?
Thanks for answers.
