I am evaluating Pingrow and I like the flexibility to play with both visual elements and HTML/CSS. I am following the tutorial Summer Nights CSS Grid Tutorial, currently working on video 9: making the page responsive. I followed the instructions and I do have two rules(copies of the original body) for displays larger than 1200px and 992px.They both have their media query setup. I am performing the changes in the body rule (with no media query) in order to adapt this view to screens smaller than 992. However, when I select this body rule and change the columns in the grid, the change is reflected in all the sizes. See attached picture. Any ideas?
