[英]Navigation Hides Menu Icon

问题描述

我创建了一个响应式导航栏，但是在移动视图中时，菜单上的标题在显示时隐藏了菜单图标。 下面是正在发生的事情的图片（我还没有足够的声誉可以发布图片，所以有链接）和一支电笔。 我尝试添加填充并调整float属性，但没有任何效果。 谢谢！

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

响应式视图。 在按钮的右上角或单击该按钮时在那儿

您的菜单将显示或隐藏。 在移动视图中，使用边距顶部显示

完全按下菜单切换按钮。 这是正常的响应菜单功能。

将第16行更改为： 

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

然后，为使外观更好，请对菜单图标使用相同的蓝色； 将第132行更改为： 

background-color: #4484CE;

您可以再走一步，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;}

更新：

在所有media query @media添加以下代码，从而在mobile device上使用burger-menu时将其顶部对齐。 

@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;
    }
