sass expands the nesting ie .foo { .bar { color: red; } } becomes .foo .bar { color: red; } The first case modern browsers can handle, but versions of Chrome upto some in early 2023 still can't – and that includes a lot of Android installs as I experienced. Once those browser versions roll off we will be able to remove sass altogether.
