This is essentially website development at this point. You will need to understand the CSS cascading rules and specificity. Those are (in brief) anything read in later (from the same or another CSS file) is used if it has the same or higher specificity. Google “css selector specificity rules” for more info. However, keep in mind that you can also set properties in different selectors that effectively change the look of the same element.
You might want to use a tool designed to help figure that out if you cannot do it by looking at the files and the selectors you have created. You will see recommendations on various tools and methods for understanding this when you Google for the keywords above.
