CSS3模拟侧滑菜单

本文主要是介绍CSS3模拟侧滑菜单，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在APP应用上，常见的一种导航方式是侧滑导航，效果类似于这样：
nav-slide

用CSS3可以对其进行模拟，代码如下：
HTML：

<nav><div id="toggleMenu"><span id="hide"></span><span id="show"></span></div><ul id="list"><li><a href="#">首页</a></li><li><a href="#">问题</a></li><li><a href="#">文章</a></li><li><a href="#">关注</a></li><li><a href="#">发现</a></li></ul></nav>

CSS:

nav{width: 100%;height: 50px;background-color: rgba(26,188, 156, 0.75);position: relative;}div{position: absolute;height: 100%;width: 50px;left: 20px;cursor: pointer;-webkit-transition: transform 1s;-moz-transition: transform 1s;-ms-transition: transform 1s;-o-transition: transform 1s;transition: transform 1s;}#hide,#show{display: block;height: 3px;background-color: #FFF;position: absolute;top: 50%;-webkit-transition: opacity .5s;-moz-transition: opacity .5s;-ms-transition: opacity .5s;-o-transition: opacity .5s;transition: opacity .5s;}#show{width: 20px;left: 15px;opacity: 0;}#hide{width: 30px;left: 10px;margin-top: -1.5px;}#hide::before,#hide::after,#show::before,#show::after{content: "";display: block;height: 3px;background-color: #FFF;position: absolute;}#hide::before,#hide::after{width: 30px;}#show::before,#show::after{width: 25px;}#hide::before,#show::before{top: -10px;}#hide::after,#show::after{top: 10px;}#show::before{-webkit-transform: rotate(35deg) translateX(5px);-moz-transform: rotate(35deg) translateX(5px);-ms-transform: rotate(35deg) translateX(5px);-o-transform: rotate(35deg) translateX(5px);transform: rotate(35deg) translateX(5px);}#show::after{-webkit-transform: rotate(-35deg) translateX(5px);-moz-transform: rotate(-35deg) translateX(5px);-ms-transform: rotate(-35deg) translateX(5px);-o-transform: rotate(-35deg) translateX(5px);transform: rotate(-35deg) translateX(5px);}ul{list-style: none;background-color: #455552;position: absolute;top: 34px;left: -200px;width: 74px;-webkit-transition: all .5s ease-in-out;-moz-transition: all .5s ease-in-out;-ms-transition: all .5s ease-in-out;-o-transition: all .5s ease-in-out;transition: all .5s ease-in-out;}li{margin: 0;padding: 0;position: relative;left: -40px;text-align: center;width: 112px;}a{text-decoration: none;color:#FFF;display: inline-block;height: 40px;line-height: 40px; }li:hover{background-color: rgba(26,188, 156, 0.75);}

JavaScript控制一下事件：

var toggle = document.getElementById("toggleMenu");var list = document.getElementById("list");var hide = document.getElementById("hide");var show = document.getElementById("show");var isHidden = true;window.onload = function() {toggle.onclick=function(){if(isHidden){list.style.left="0px";isHidden = false;hide.style.opacity=0;this.style.mozTransform = "rotate(180deg)";this.style.msTransform = "rotate(180deg)";this.style.oTransform = "rotate(180deg)";this.style.webkitTransform = "rotate(180deg)";this.style.transform = "rotate(180deg)";show.style.opacity=1;}else{list.style.left="-200px";isHidden = true;hide.style.opacity=1;this.style.mozTransform = "rotate(0deg)";this.style.msTransform = "rotate(0deg)";this.style.oTransform = "rotate(0deg)";this.style.webkitTransform = "rotate(0deg)";this.style.transform = "rotate(0deg)";show.style.opacity=0;}}}
