> nope, we currently have decided to counteract. The reason is we render boxes which should be closable and there can be cases when box in user zoomed page can grow too big and hide close button. Also we do not want our boxes to be rendered too small. The solution is to detect browser zoom and apply correction to our boxes keeping them visually constant, desired size.

How is a large zoom different from user changing their window to a smaller size that your box would simply overflow? As I mentioned above, I believe sites should just be responsive to the viewport size, regardless of it being from zooming or window resizing. Am I missing something?

So why do you use `zoom` at the first place?
