The challenge I would like some assistance with is as follows:

We have a number of ,Net applications that we have created and modified to work in an iFrame on our customers sites (which we host).

The skin round the iFrame depends on the customer - each has a specific look and feel and format for buttons in particular.

We create the skins in Artisteer and install the appropriate skin in each customers portal.

Is there a way that we can use the button design from the skin in that customers iFrame.

For example, customer a has blue buttons on the site and customer b has green buttons.  How do we set up our .Net VB structure so that it recognizes the css file for the particular portal it is appearing on?  The source code for the iFrame is in the same location - we would like to be able to tell it to get the skin.css from the portal on which it is appearing - or set it to be a skin of a certain name in a certain location (a.css would be Customer a's skin, b.css would be Customer b's skin).

I am trying to get to a point where I can create a skin for a client, and have the iFrame pick up the skin.css from the portal, or drop a copy of it in a predefined location, and, on that clients site, the buttons will look like the rest of the web page.  This would also allow fast changing of the button design, just by overwriting the skin.css file with a new one.

We have been messing with Master Pages and so forth but have ended up in a mess.

Thanks
