Integrating vB's style system into non-vB site

[Dave Rosteck]

Could someone with site skinning experience explain how Tekken Zaibatsu managed to integrate their vB styles into their main non-vB site? As you can see, you have the option to change styles from the main non-vB site which reflects on the forums as well. If it helps, my non-vB site does not currently have styles so I'm open to any sort of method required to make this possible.

Here's what the webmaster said about it however, it's quite over my head at this point.

Just get your site skin system to use the same IDs as the forum styles so the cookie servers as an identifier for both site and forum skins.

Thanks in advance for the help.
