CSS选择最多N个层次的嵌套元素 [英] CSS select nested elements up to N levels deep

问题描述

我有许多嵌套元素，并且我试图仅选择前N个级别.下面显示了一个工作示例，在这里选择前7个级别并设置其样式.正是我想要的方法，但是我希望可以有一种简化的选择这些元素的方法.

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.

在我的实际用例中，我不知道嵌套元素的总数，并且我试图选择前50个级别，因此使用上述方法会很混乱.不幸的是，我无法在应用程序中更改HTML，因此它必须是仅CSS的方法.谢谢.

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 my application, so it needs to be a CSS only method. Thanks.

.container > div,
.container > div > div,
.container > div > div > div,
.container > div > div > div > div,
.container > div > div > div > div > div,
.container > div > div > div > div > div > div,
.container > div > div > div > div > div > div > div {
  border-left: 1px solid;
  padding-left: 15px;
}

<div class="container">
  <div>
    A
    <div>
      B
      <div>
        C
        <div>
          D
          <div>
            E
            <div>
              F
              <div>
                G
                <div>
                  H
                  <div>
                    I
                  </div>
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

推荐答案

到目前为止，在所有CSS版本中，根据我所知 后代级别选择器 ，这都是不可能的>选择所有达到指定级别的元素的计划很快就不会实现.

This is impossible in all CSS versions up to present and as far as I know a Descendant Level Selector that selects all elements up to a specified level is not planned to be implemented anytime soon.

您可以做的是为要选择并使用的所有元素设置一个类:

What you can do instead is set a class to all the elements you want to be selected and use:

.container .class {
    border-left: 1px solid;
    padding-left: 15px;  
 }

如果您无法在HTML中进行任何更改或使用JavaScript，那么目前最好的选择就是

If you can't make any alterations in your HTML or use JavaScript, then what you currently have is your best bet.
