Changing Only the CSS/Color Scheme
 

I have made several alternative color schemes for my forum. The only customizations were made on the main css page. Is it possible to only import the css style changes? For example, lets say I have two different templates with layout differences. I want to apply the same color scheme to both, but don't want to make any changes to any of the other template files. What would be the fastest/easiest way to do this?

I think you can try to upload the style with colors and make it child under the parent style. the parent style is the one with different layout. But you still have to download the style with colors before uploading it . I dont know it works or not but you can try.
