我想在较小的屏幕上将菜单项显示为单独的行。这是非常基本的,看到很多地方。我想要的效果是:
到目前为止(代码如下),菜单项只显示在徽标旁边(这就是它们在桌面上的用途)。
此外,我还需要在菜单项中添加背景图像。一个图像填满整个区域而不是每个菜单重复的图像
我已添加:
<meta name="viewport" content="width=device-width, initial-scale=1">
这是我的fiddle
//make the topnav responsive for mobile screens
function topNav() {
var x = document.getElementById("myTopnav");
if (x.className === "myTopnav") {
x.className += " responsive";
} else {
x.className = "myTopnav";
}
}

这是我的解决方案(更改了标记,js和css):
HTML:
<div class="topnav" data-mobile="false">
<nav>
<div class="myTopnav" id="myTopnav">
<a class="link" href="index.html">HOME</a>
<a class="link" id ="selected" href="about.html">ABOUT</a>
<a class="link" href="expertise.html">EXPERTISE</a>
<a class="notlink" href="index.html"><img src="https://www.google.com/logos/doodles/2017/earth-day-2017-5650394117046272-s.png"></a>
<a class="link" href="industries.html">INDUSTRIES</a>
<a class="link" href="friends.html">FRIENDS OF MARY</a>
<a class="link" href="contact.html">CONTACT</a>
<a href="javascript:void(0);" class="icon" onclick="topNav()">☰</a>
</div>
</nav>
<nav id="mobile-menu">

<a class="link" href="friends.html">FRIENDS OF MARY</a>
<a class="link" href="contact.html">CONTACT</a>
</nav>
</div>
JS:
function topNav() {
var topNav = document.querySelector('.topnav');
topNav.dataset.mobile = (topNav.dataset.mobile == "false") ? true : false;
}
CSS:

在此之后,您需要在展开移动设备菜单时将其正确放置在以下内容上。

以下是fiddle
您需要为顶部栏添加flex-direction:column
,以便将其显示为移动设备的列。
.topnav nav div{
flex-direction:column;
}
.myTopnav.responsive a.link:first-child{
margin-top:30px;
}
.myTopnav.responsive a.link{
width : 100%;
}
.myTopnav.responsive a.notlink{
width: 70%;
position: absolute;
top: 0px;
text-align: center;
}
