At this point you will have probably noticed that we use only two CSS files (or three depending on the template), one for K2 (k2.css), another one (template.css) for everything else and in some cases the colorvariations.css file.
But what happens when you want to make minor changes but still want to keep getting updates without breaking something?
The answer is very, very simple. In all of our templates you will find a file called custom.css under the css folder and a custom.js file under the js folder.
When you upgrade the template (using the upgrade package) you will notice that your custom styles have remained intact while getting the newest version of the template.
