I see, now I understand.

As for the browser cache problem: This Chrome extension is your friend: 

https://chrome.google.com/webstore/detail/clear-cache/cppjkneekbjaeellbfkmgnhonkkjfpdn?hl=en

I use it all the time I change the CSS or a JS file. Having the "Developer Tools" open in Chrome helps as well 
(cache is then turned off). Firefox has similar extensions.
