First of all, that is pretty cool (and easy) @MagikSwapna
However, it only happened on my home page. I actually only need my css tweak for the compare page pop-up window.
Here are my CMS > Pages options:
Customer Service customer-service
Enable Cookies enable-cookies
My Site home
404 Not Found 1 no-routePreview
Second, I see that the css file to be loaded will live in `/skin/frontend/base/default/css/` . What happens to that css file when I upgrade Magento?
