我的汉堡菜单适用于除iPad以外的所有设备

Question

我用HTML和CSS做了一个菜单。它使用链接。它适用于任何设备，但在 768px 时，菜单停止工作，我找不到原因。

谁能帮我？

<a class="klsm" href="#">KSLM</a>
<button class="navbar-toggler" id="#tog" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>        
</button>

您正在使用"navbar-expand-md"。但是，您想在 Ipad 肖像(768(中显示汉堡菜单，因此请在 lg 屏幕 (992px( 中展开菜单。改用类"navbar-expand-lg">
