I'm a Java developer new to WordPress theme development. I understand the Loop, can find my way around PHP fairly well, but where I'm stuck is at style.css. I was working with the twentyfourteen theme, trying to re-work the look-and-feel, as an exercise, but there are 4200 lines of code, hundreds of class entries! Help!! How does anyone get their head around all those classes? What is the typical workflow for producing a style-sheet like this. By hand with a text editor? Sass? Some kind of wysiwyg editor? What is the right path for this aspect of WP theme development??
Thanks in advance!
