This colorful little exercise actually attempts to show where the Core and Module CSS and TPL files are located. The thing is, Core really mean Core and Core Module. Together, these are refered to as Core. Module refers to contributed modules and their corresponding files that may or may not supersede the core files. Then, there are the Theme files. These can trump all the rest of the files’ styles if the naming conventions are followed properly. This too-busy diagram also attempts to help me see how I deal with many colors, shapes and layering. I’m not a design guy and I don’t really care for design, nor am I any good at it. But, I have to learn some of it.
Inheritance rev7 – Copy – this is the actual Visio diagram. rename it to .vsd and you can see this up close.
