Dynamic CSS - Common approach for code-igniter?

[eluser]sl3dg3hamm3r[/eluser]
Hey there

Here comes right my second question :-)
Additional data like css and images I do store now on the same level as where you would find the system-folder.

But now I encounter the situation where I would like to manipulate some variables in css, before it is sent to the browser. E.g. if there is a background-picture defined which is language-depending, I need to set that picture first with code-igniter.

What is there the approach? Shall I treat in that case CSS as a view? Or what are the common approaches here in that case?

Any tipps highly appreciated!
