If you want to be modular, you must have conventions. This is to prevent double spacing when you put two elements one next to another without additional styling. I also use to have ELEMENT > *:first-child {padding-top: 0} on containers, so that I can control the padding of the container and without having to consider what element I place into it. There's a lot of best practices I made part of my workflow, perhaps I should write a blog post about it.
