javascript - 移动导航栏工作不正确

Question

我正在用 js、css 和 html 创建一个响应式导航栏。我现在有一个问题，当屏幕变成 x 大小（我定义为最大宽度的大小）时，会弹出响应式导航栏。虽然，只有最后一个锚（Loja）出现在上面。我希望它显示为 flex 和列的 flex-direction。如打印所示：

您的所有<li>元素都具有完全相同的位置，因此它们相互叠加。如果我删除背景，您可以清楚地看到这一点（参见底部的图像）。

你需要选择你的<ul>元素，而不是<li>元素

/* @media screen and (max-width: 1250px){
    nav ul.ulSecções li { */
@media screen and (max-width: 1250px) {
  nav ul.ulSecções {
