If you're this concerned about the readability and/or modularity of your code, you should be using a css preprocessor like less/sass/scss. Even if you have css all dolled up like this, it will still take longer to update and manage than it would if you were using mixins and variable declarations. Yes it is one more thing in the pipeline. But you should be minifying your CSS anyway, so you're already compiling your css in a way.
