I have looked all over this forum and still have not found any info that works for me. I am trying to customize D7 using Firefox's "firebug" add-on that allows you to select an area of a website to change its CSS properties. Every time i do this, it tells me that the file to change for any part of D7 is located in the "cache_public" folder. But when i modify the css files in the cache folder, it only changes for firefox and not other browsers. I know i'm doing something wrong here.
What is the correct and easiest way of creating a template for D7? Can i get some easy steps to follow? (i am very familiar with D6 but i am a newbie to D7)
