My question is if everything is suppose to be in 4px or 8px increments does that mean even the height of sections or containers? For instance if you wanted to have a section that filled the viewport you would set that section to 100vh. However that would break the baseline grid. I'm just confused because some of the guidelines seem to be counterproductive to responsive design. For instance setting an exact container / section height would mean resizing them all at specific breakpoints.
