htaccess for ip and referrer

In my development server the, the referrer name will look like dev.host.in and the ip will look like 123.456.456.111/dev/

When 开发者_JS百科I access the site through the ip address, the site is not getting display normally because the css file path is wrong in this case.

How to set a .htaccess file to incorporate this?

You don't need an htaccess to do something like that. Add <base href="base url"> to your html file.
