这很多但我想展示它，因为我不知道问题出在哪里。我将尝试解释我在HTML中使用的类的位置

这是我在项目中使用的唯一的2个孩子，他们不起作用。

.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的类从第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。在那些列表元素中，第3个和第4个元素（两个不同的段落）应该被nth-childs选中。不要担心列表内容类的div，我已经尝试将其删除但css仍然无效。

如果有人可以帮助我，我会非常感激！

Answer 1

我认为您的问题是，您试图直接在<li>内<ul>设置alm-listing > li的样式<li>，但您有.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 } }标签在另一个div内。

试试这个

// Upload a file to an HTTP server.
pplx::task<void> UploadFileToHttpServerAsync()
{
    using concurrency::streams::file_stream;
    using concurrency::streams::basic_istream;

    // To run this example, you must have a file named out.txt in the current folder.

    // Open stream to file.
    wstring filePath = L"out.txt";
    return file_stream<unsigned char>::open_istream(L"filePath").then([](pplx::task<basic_istream<unsigned char>> previousTask)
    {
        try
        {
            auto fileStream = previousTask.get();
            http_client client(L"http://localhost:80");
            return client.request(methods::PUT, L"filePath", fileStream).then([fileStream](pplx::task<http_response> previousTask)
            {
                fileStream.close();

                std::wostringstream ss;
                try
                {
                    auto response = previousTask.get();
                    ss << L"Server returned returned status code " << response.status_code() << L"." << std::endl;
                }
                catch (const http_exception& e)
                {
                    ss << e.what() << std::endl;
                }
                std::wcout << ss.str();
            });
        }
        catch (const std::system_error& e)
        {
            std::wostringstream ss;
            ss << e.what() << std::endl;
            std::wcout << ss.str();

            // Return an empty task.
            return pplx::task_from_result();
        }
    });

对，所以我觉得我发现了问题。它不是CSS。我取消了我的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（缩小版）的备份。当我将缩小版本上传到我的网站时，nth-childs就像他们应该的那样工作。我将缩小后的备份解压缩并将其上传到我的网站，瞧，我的代码停止了工作...我无法相信这甚至是一件事。对于想知道我曾经在哪些网站进行统一的人，他们在这里; unminify.com和codepen.com的编辑器（整洁的CSS）。

Welp我想我必须重新开始; /

：n-child不起作用
