Hello @BeatlesBOB   Try setting overflow-x to hidden on your .wrapper - that overflow is probably what's causing the whole layout to shift in that view. It does fix it for me - is that better for you, too?   Edit: I suppose you are talking about the dev-tools opening on press of F12 (Chrome on Windows does that) and the mobile view of the dev-tools accordingly-.   .wrapper{ display: flex; flex-wrap: nowrap; overflow-x: hidden; }
