I am running Magento 1.9 in a multiple store environment. I am trying to have the exact same design for every store, thus each store uses the same Theme.
However, I need to make some slight changes in the CSS files for a specific store,but at the moment it is not possible because the CSS resources are being shared among each store.
To address this issue, I have duplicated the theme in the following path:
And then from Admin>System>Design, I have told Magento to use customtheme2 to that specific store.
Now I can easily change the CSS file for that store.
My Question: Is this the correct (Standard) Approach to address my need?
