I am building a Repository of user-control and wanted to find out the best way to server the CSS classes.

1. Should I load them ALL into 1 giant External CSS File and load it whenever a given user-control is rendered?
2. Should I load them into 1 External CSS File per user control?
3. Should I embed the CSS into the Markup of the user-control with RadCodeBlocks?

I cant see doing inline as a benefit as it would make a nightmare to modify an tweak.

This is open to all users to give me some pros and cons of each...

I'm leaning to #3 for manageability...
