我正在使用Zurbs响应式框架基础。
我决定让顶栏在更大的屏幕上变成汉堡包图标，因为我有很多菜单选项，当他们在平板电脑等中型屏幕上观看网站时，它们会向下推两行。
所以我找到了确定大小的媒体查询
@media only screen and (min-width: 40rem) {...}
我将其更改为1025像素，现在它显示在1025像素及更小的屏幕上。问题是，在较小的屏幕上打开并变大时，实际菜单将无法打开或保持打开状态。
我认为这与某个地方的最大宽度设置有关，但我在该媒体查询中找到的最大宽度并没有改变任何东西。
这是整个查询

您不必“破解”Tob Bar css以在某些断点上显示移动布局。您所要做的就是编辑现有的Foundation设置css文件。
因此，例如，Top Bar有一组可用的SCSS变量，你可以在这里查看它们 - follow the instructions
您正在寻找的是：
#include <iostream>
#include <iomanip>
#include <chrono>
#ifdef WIN32
#define localtime_r(_Time, _Tm) localtime_s(_Tm, _Time)
#endif
int main()
{
tm localTime;
std::chrono::system_clock::time_point t = std::chrono::system_clock::now();
time_t now = std::chrono::system_clock::to_time_t(t);
localtime_r(&now, &localTime);
const std::chrono::duration<double> tse = t.time_since_epoch();
std::chrono::seconds::rep milliseconds = std::chrono::duration_cast<std::chrono::milliseconds>(tse).count() % 1000;
std::cout << (1900 + localTime.tm_year) << '-'
<< std::setfill('0') << std::setw(2) << (localTime.tm_mon + 1) << '-'
<< std::setfill('0') << std::setw(2) << localTime.tm_mday << ' '
<< std::setfill('0') << std::setw(2) << localTime.tm_hour << ':'
<< std::setfill('0') << std::setw(2) << localTime.tm_min << ':'
<< std::setfill('0') << std::setw(2) << localTime.tm_sec << '.'
<< std::setfill('0') << std::setw(3) << milliseconds
<< std::endl;
}

如果您仅使用CSS下载，则可以在2个位置更改CSS更改顶部断点。这是发布回答的链接
