如何修复导航栏？身高问题答案

【问题标题】：How can i fix the navbar? Problem with height如何修复导航栏？身高问题

【问题描述】：

我正在尝试将我的菜单水平放置在移动版本上：

但是，当我将值修改为：

.left-side（白色）：宽度：100% 高度：40vh

和

.menu（右侧黑色）：宽度：100%；高度：60vh；

但是当我这样做时，菜单会中断。右侧菜单位于顶部。

我已经看到，如果我将导航的高度更改为 100%，它会起作用。但是当我回到桌面版本时，当使用元素检查器时，菜单一直在顶部（图层）（我无法选择文本）。我尝试使用 z-index 并没有。我认为导航应该是 height: 80px in desktop and 100vh 但我不知道。

        main {
            .container-education {
                width: 90%;
                flex-direction: column;
            }
        }

    }
}

const toggle = document.getElementById("toggle");
const leftSide = document.getElementById("left-side");
const navbar = document.getElementById("navbar");
const menu = document.getElementById("menu");

toggle.addEventListener("click",  () =>{
    // navbar.classList.toggle("active")
    toggle.classList.toggle("active");
    leftSide.classList.toggle("left-effect");
    menu.classList.toggle("right-effect");;
})

希望有人可以帮助并理解我的帖子。如果没有，我会尝试更具体的

谢谢

感谢您的建议@AymanMorsy，这是我与 SASS 的第一个项目。我读过嵌套选择器是正确的形式。我在这里读到：sass-lang.com/documentation/syntax，在 SCSS 中就像我的帖子。现在我很困惑。谢谢

【解决方案1】：

您可以在媒体查询中使用以下代码

我相信要让导航切换 btn 正常工作，您需要在其中添加一点 z-index

nav .left-side {
    width: 100%;
    height: 40vh;
}

nav .menu {
    width: 100%;
    height: 60vh;
    margin-top: 45vh;
}

nav .containerIconMobile {
    z-index: 9;
}

谢谢@Rahul！！！ margin-top 这是我需要的！！但我不明白为什么：S。如果你能解释我，我将不胜感激。再次感谢！
@ZeR0ByTe 因为你的#left-side 和#menu 是position absolute 所以为了出现在另一个下面，我们必须添加底部一个top 或margin-top，高度为@987654330 @ 或大于它，所以它出现在#left-side 下面
