很多，但我想展示它，因为我不知道问题出在哪里。我将尝试解释我使用的类在 HTML 中的位置

这些是我在项目中使用的唯一 2 个 nth-child ，它们不起作用。

.alm-listing > li:nth-child(4) {
    padding: 0 10px;
    margin-top: 5%
}

.alm-listing > li:nth-child(3) {
    position: absolute;
    top: 20%;
    left: 0;
    right: 0;
    color: #fff
}

.alm-listing 类从第 4 个 HTML 元素开始；无序列表 那么 css 应该选择该 UL 中的列表元素。在这些列表元素中，第 n 个孩子应该选择第 3 和第 4 个元素（两个不同的段落）。不用担心带有 list-contents 类的 div，我已经尝试将其取出，但 css 仍然无法正常工作。

如果有人可以帮助我，我将不胜感激！

Answer 1

我认为你的问题是你试图直接在 <ul> 内设置 <li> 的样式，就像 alm-listing > li 所做的那样，但是你在另一个 div 内有 <li> 标签。

试试这个

.alm-listing > div > li:nth-child(4) {
    padding: 0 10px;
    margin-top: 5%
}

.alm-listing > div > li:nth-child(3) {
    position: absolute;
    top: 20%;
    left: 0;
    right: 0;
    color: #fff
}

Answer 2

是的，我想我找到了问题所在。这不是 CSS。我精简了我的 CSS，以便我可以更轻松地安排一些媒体查询。在 unminify 之后是问题开始的时候。我从 2 天前找到了我的 CSS（缩小）的备份。当我将缩小版本上传到我的网站时，nth-childs 会像他们应该的那样工作。我取消了缩小的备份并将其上传到我的网站，瞧，我的代码停止工作......我不敢相信这甚至是一件事。对于想知道我曾经取消缩小哪些网站的人，他们在这里； unminify.com 和 codepen.com 的编辑器（整洁的 CSS）。

好吧，我想我必须重新开始；/
