Foundation Top-Bar 在某些尺寸下不起作用

Question

我正在使用 Zurbs 响应式框架基础。

我决定希望顶部栏在更大的屏幕上变成一个汉堡图标，因为我有很多菜单选项，当在平板电脑等中等大小的屏幕上查看网站时，它们会向下推到两行。

所以我找到了正在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 像素或更小的屏幕上。问题是实际菜单在较小的屏幕上打开并变大时不会打开或保持打开状态。

我认为这与在某处设置的最大宽度有关，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

@media only screen and (min-width: 1024px) {
  .top-bar {
    background: #333333;
    overflow: visible; }
    .top-bar:before, .top-bar:after {

Answer 1

如果您只使用 CSS 下载，您可以在 2 个地方通过 CSS 更改来更改顶栏断点。这是已发布答案的链接

Answer 2

您不必“破解” Tob Bar css 即可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。

例如，Top Bar 有一组可用的 SCSS 变量，您可以在此处查看它们 - http://foundation.zurb.com/docs/components/topbar.html

你要找的东西是：

$topbar-breakpoint: #{lower-bound($medium-range)}; // Change to 9999px for always mobile layout
