Question

我创建了一个自适应导航栏，但是当它处于移动视图中时，菜单上的标题会在显示时隐藏菜单图标。下面是一张正在发生的事情的图片（我没有足够的声誉来发布图片，所以有链接）和一个代码笔。我试过添加填充和调整浮动属性，但没有任何作用。谢谢！

单击菜单图标后：

Answer 1

It responsive function in toggle button to toggle menu show or hide in

响应式视图。在右上角按钮或那里点击该按钮

您的菜单将显示或隐藏。在移动视图中使用margin-top显示

菜单切换按钮完全显示。这是一个正常的响应菜单功能。

Answer 2

将第16行更改为：

#nav > a {
display: none;
z-index:99;}

然后为了让它看起来更好，请使用相同的蓝色作为菜单图标;将第132行更改为：

background-color: #4484CE;

您可以更进一步使用：active或：visited状态，或者将Jquery用于is-clicked，is-open或其他状态，例如

#nav > a:active{background-color: #93C178;}

在您的所有media query @media中添加以下代码，这样就可以在burger-menu上使用mobile device时将其与@media only screen and ( max-width: 640px ) { #nav { font-size: 12px; } #nav > ul > li > a { font-size: 12px; } #nav li ul a { font-size: 12px; } #nav > a{ position:absolute; z-index:9; right:0; top:0; background:#111; } }对齐。

#nav {
