Well, I started to do responsive design. This is not hard at all. Being all mathematical in the past percentages is really easy for me. The thing I don’t understand is people using really shitty values at first.
<div class="content"> has to be 31.67777875%? It’s a baseline-ish measure…. Just go for something like 31.25%. This means just couple of pixels difference, but as this is one of the core values your grid will rely on, you don’t need to overcomplicate.
PS. Found this RQRWD site. Very straightforward, beautifully made, but maybe too simple as opposed to Gridset which is overcomplicated for most of the tasks.
Should probably try and make something inbetween.
