换了一些样式后,手机汉堡包图标不显示了,怎么调回来?另外,在菜单上方和下方添加更多空白但保持位置不变的最佳方法是什么?

HTML:

<input type="checkbox" id="xBxHack" />
<nav id="mainNav" class="mainNav">
<div class="container">
<div class="logo"><a href="#">my<strong>Nav</strong></a></div>
<label class="navBars" for="xBxHack">
<i class="fa fa-bars"></i>
</label>
<ul id="menu" class="menu">
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Work</a></li>
<li><a href="#">Contact</a></li>
</ul>
</div>
</nav>

CSS:

.mainNav {
background: #fff;
color: #fff;
max-height: 70px;
position: relative;
top:35%;
}
.mainNav a {
text-decoration: none;
}
.mainNav .logo {
display: inline-block;

}
.mainNav .logo a {

#xBxHack {
visibility: hidden;

position: absolute;

}
#xBxHack:checked ~ nav .menu {
display: block;
}

.container {
max-width: 960px;
margin: 0 auto;
padding: 10px;
}

@media screen and (min-width: 600px) {
.mainNav {
overflow: hidden;
}
.mainNav .navBars {
display: none;
}
.mainNav .container {
padding-top: 0;
padding-bottom: 0;
}
.mainNav .logo {
margin: 10px 0;
}
.mainNav .menu {
display: block;
box-shadow: none;
border: none;
float: right;
/*POSITION*/
position: static;
}
.mainNav .menu li {
display: inline-block;
}
.mainNav .menu a {
border: none;
padding: 20px 10px;
}
}

JS:

$(document).ready(function() {
"use strict";
var myNav = {
init: function() {
this.cacheDOM();
this.browserWidth();
this.bindEvents();
},
cacheDOM: function() {
this.navBars = $(".navBars");
this.xBxHack = $("#xBxHack");
this.navMenu = $("#menu");
},
browserWidth: function() {
$(window).resize(this.bindEvents.bind(this));
},
bindEvents: function() {
var width = window.innerWidth;

if (width < 600) {
this.navBars.click(this.animate.bind(this));
this.navMenu.hide();
this.xBxHack[0].checked = false;
} else {
this.resetNav();
}
},
animate: function(e) {
var checkbox = this.xBxHack[0];
!checkbox.checked ?
this.navMenu.slideDown() :
this.navMenu.slideUp();

},
resetNav: function() {
this.navMenu.show();
}
};
myNav.init();
});

在这个 jsfiddle 中,您可以看到当屏幕很小时图标不会出现:https://jsfiddle.net/quehf3x9/

最佳答案

首先确保您正在加载 Font Awesome图书馆。没有在 JS Fiddle 示例中加载它。所以我包含了一个指向 CDN 的链接.

其次,为导航栏的 CSS 添加宽度、高度和背景颜色:

.mainNav .navBars {
width: 30px;
height: 30px;
color: #111;
}

查看我更新的 JS Fiddle一个工作示例。
