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：

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); }
