我有一个问题，我有5个div和同一个类，它是这样的：
div > form > div.prdctfltr_filter_wrapper.prdctfltr_columns_1 > div > div > div.prdctfltr_add_scroll.prdctfltr_max_height.prdctfltr_down
我试图添加nth-child(1)，但似乎我用错了方法：
div > form > div.prdctfltr_filter_wrapper.prdctfltr_columns_1 > div > div:nth-child(1) > div.prdctfltr_add_scroll.prdctfltr_max_height.prdctfltr_down
我只想在第一个上应用一个样式，而不是全部5个。我如何选择第一个？
更新：添加HTML标签
我想选择的款式是第一种：

</div>您需要选择.prdctfltr_filter类并使用:first-of-type或:first-child选择器。CCD_ 5和CCD_。
然后在找到的第一个元素中选择.prdctfltr_add_scroll类。
.prdctfltr_filter:first-of-type .prdctfltr_add_scroll {
/* Your styles here */
}

根据经验，尽量不要深入到3个级别selector1 selector2 selector3 { }。
