At the moment I use classic classes (semantic) and atomic css for positioning. I can't figure out how to change, for example, margin-top at a few blocks? Is it really necessary to manually change the class mt(25px) all my units?
<div class="box mt(25px)"></div>
<div class="box fl mt(25px)"></div>
<div class="block mt(25px)"></div>
For example, I need to edit margin of only the div with the class box.
