所以首先我使用 html css 和 js 构建一个页脚。然后我发现了 Bootstrap 并尝试使用 Bootstrap、移动优先设计来创建它 <576px.
在发现 bootstrap 之前，我已经使用 css 在中型和大型桌面中完成了页脚。现在我已经使用引导程序在小屏幕上完成了页脚。不过，我对如何将布局从小屏幕更改为中型和大屏幕并不感到困惑。
所以我想保留这两种设计，但我无法这样做。我知道如何使用引导程序创建中型和大屏幕，但现在我已经编写了小屏幕代码，我不知道如何构建中型和大屏幕的响应代码。
所以基本上应该如此，中型和大型屏幕将使用 1 行 3 列 4 的网格。 但我没能找到如何从我当前的代码转换它。

这是中号大号设计 中大屏
这就是小设计 小屏幕
所以基本上我想保留这两种设计，但我无法做到。我实际上有一个技巧，但它基本上分别创建了 2 个设计，而不是使其响应。所以我可以为小型设计做
d-md-none那你不应该先做1行3列4吗？中大屏设计完成后可以调整设计。然后你可以从这些代码中调整小屏幕。小屏幕设计需要改变，但就是这样
