问题 I have a number of nested elements, and I'm trying to select only the first N levels. The below shows a working example, where I'm selecting the first 7 levels and styling them. That works exactly how I want, however, I was hoping there was a simplified way of selecting these elements. In my actual use case, I don't know the total number of nested elements, and I'm trying to select the first 50 levels, so using the above method would be quite messy. Unfortunately, I can't change the HTML in
