is it possible to combine css's

[Sean S]

Hello,

I have a quick question and am curious to know if it is possible to do. One of the websites that I'm working on uses two to three other php scripts that are not integrated with vbulletin. However, I like those other scripts to use the same CSS as the vbulletin's. I know that this can be done by simply adding a link of the css to the other scripts or just copy paste the css to the other scripts css file. But the problem is that the site has several skins, light/dark, and I want the css files for those scripts to change for those other scripts if the user changes the default skin.

I'm also thinking that some cookie sessions should be involved so that the site would remember which skin the user has selected, so that the css could change accordingly with the other scripts. I also know that I have to make vbulletin so that it saves the CSS's as files.

I wish I could explain my idea better, would something like this be achievable? or better yet, is there a easier way to do this? thanks.
