下拉移动菜单未推送内容

Question

我希望我的移动菜单将其下方的内容下推。这里的内容是页脚。我在这儿做错什么了？

Answer 1

这里的问题是规则grid-template-rows: 40px auto 40px;的最大宽度：840px可以与header {display: none; }一起使用。

使用这2条规则，当您的最大宽度为840px时，您的第一行将成为.menu，并将其高度设置为40px。

这是我所说的一个例子。我创建了4行，将display:none放在第一行：您会看到第二行采用第一行的规则。

#grid{
 display: grid;
 grid-template-rows: 20px 100px 40px 100px;
}
.a_1{
  background-color:yellow;
  display:none;
}
.a_2{
  background-color:orange;
}
.a_3{
  background-color:blue;
}
.a_4{
  background-color:red;
}

<div id="grid">
  <div class="a_1"></div>
  <div class="a_2">I'm the second row but I'm height only 20px</div>
  <div class="a_3"></div>
  <div class="a_4"></div>
</div>

因此，解决方案可能有所不同：删除grid-template-rows规则（也删除网格行：-1；在页脚中），或者在最大宽度为840px时更改该规则。这取决于您的布局以及您需要做什么。

我将举例说明更改规则grid-template-rows，并添加：

@media (max-width: 840px) {
  .wrapper{
    grid-template-rows: auto 40px;
  }
}

    const triggerButton = document.getElementById('triggerButton');
    triggerButton.addEventListener('click', () => {
        const x = document.getElementById("menu");
        if (x.className === "menu") {
            x.className += " responsive";
        } else {
            x.className = "menu";
        }
    })
