1、新建html文档。
2、书写hmtl代艨位雅剖码。<div class="nav"> <button class="btn-nav"> <span class="icon-bar top"></span> <span class="icon-bar middle"></span> <span class="icon-bar bottom"></span> </button></div><div class="nav-content hideNav hidden"> <ul class="nav-list"> <li class="nav-item"><a href="#" class="item-anchor">item 1</a></li> <li class="nav-item"><a href="#" class="item-anchor">item 2</a></li> <li class="nav-item"><a href="#" class="item-anchor">item 3</a></li> <li class="nav-item"><a href="#" class="item-anchor">item 4</a></li> </ul></div>
3、书写css代码。body, html { background-color: #14213D; hei爿讥旌护ght: 100%; width: 100%; padding: 0; margin: 0; font-family: 'Lato', sans-serif; }.nav { position: relative; width: auto; display: inline-block; border: none; }.btn-nav { position: fixed; top: 50px; left: 30px; background: transparent; border: none; padding: 10px; -webkit-transition: all .5s ease; -moz-transition: all .5s ease; -ms-transition: all .5s ease; -o-transition: all .5s ease; transition: all .5s ease; cursor: pointer; z-index: 99999; }.btn-nav:focus { outline: 0; }.icon-bar { display: block; margin: 6px 0; width: 40px; height: 5px; background-color: #FFFFFF; }.btn-nav:hover .icon-bar { -webkit-transition: all 1s ease; -moz-transition: all 1s ease; -ms-transition: all 1s ease; -o-transition: all 1s ease; transition: all 1s ease; background-color: #FCA311; }.nav-content { position: fixed; top: -100%; bottom: 0; left: 0; right: 0; background: #000000; display: block; height: 100%; z-index: 9; }.nav-list { list-style: none; padding: 0; position: relative; top: 30%; }.item-anchor:after { content: ""; position: absolute; width: 3px; height: 3px; left: 0; bottom: 0; z-index: 9; background: transparent; -webkit-transition: all 1s ease; -moz-transition: all 1s ease; -ms-transition: all 1s ease; -o-transition: all 1s ease; transition: all 1s ease; }.item-anchor { color: #fff; font-size: 30px; text-transform: uppercase; position: relative; text-decoration: none; padding: 10px; }.item-anchor:hover, .item-anchor:focus { color: #FCA311; -webkit-transition: all 1s ease; -moz-transition: all 1s ease; -ms-transition: all 1s ease; -o-transition: all 1s ease; transition: all 1s ease; }.item-anchor:hover:after, .item-anchor:focus:after { width: 100%; background: #FCA311; -webkit-transition: all 1s ease; -moz-transition: all 1s ease; -ms-transition: all 1s ease; -o-transition: all 1s ease; transition: all 1s ease; }.nav-item { margin: 40px auto; text-align: center; }.animated { display: block; margin: 0 auto; }.animated:hover .icon-bar, .animated:focus .icon-bar { background-color: #FCA311; }.animated:focus { cursor: pointer; z-index: 9999; }.middle { margin: 0 auto; }.icon-bar { -webkit-transition: all .7s ease; -moz-transition: all .7s ease; -ms-transition: all .7s ease; -o-transition: all .7s ease; transition: all .7s ease; z-index: 999999; }.animated .icon-bar { z-index: 999999; background-color: #FCA311; }.animated .top { -webkit-transform: translateY(10px) rotateZ(45deg); -moz-transform: translateY(10px) rotateZ(45deg); -ms-transform: translateY(10px) rotateZ(45deg); -o-transform: translateY(10px) rotateZ(45deg); transform: translateY(10px) rotateZ(45deg); }.animated .bottom { -webkit-transform: translateY(-11px) rotateZ(-45deg); -moz-transform: translateY(-11px) rotateZ(-45deg); -ms-transform: translateY(-11px) rotateZ(-45deg); -o-transform: translateY(-11px) rotateZ(-45deg); transform: translateY(-11px) rotateZ(-45deg); }.animated .middle { width: 0; }@keyframes showNav { from {top: -100%;}to { top: 0; }}@-webkit-keyframes showNav { from {top: -100%;}to { top: 0; }}@-moz-keyframes showNav { from {top: -100%;}to { top: 0; }}@-o-keyframes showNav { from {top: -100%;}to { top: 0; }}.showNav { -webkit-animation: showNav 1s ease forwards; -moz-animation: showNav 1s ease forwards; -o-animation: showNav 1s ease forwards; animation: showNav 1s ease forwards; }@keyframes hideNav { from {top: 0;}to { top: -100%; }}@-webkit-keyframes hideNav { from {top: 0;}to { top: -100%; }}@-moz-keyframes hideNav { from {top: 0;}to { top: -100%; }}@-o-keyframes hideNav { from {top: 0;}to { top: -100%; }}.hideNav { -webkit-animation: hideNav 1s ease forwards; -moz-animation: hideNav 1s ease forwards; -o-animation: hideNav 1s ease forwards; animation: hideNav 1s ease forwards; }.hidden { display: none; }
4、书写并添加js代码。<script src="js/jquery-2.1.1.min.js"></script><script>$(window).load(function () { $('.btn-nav').on('click tap', function () { $('.nav-content').toggleClass('showNav hideNav').removeClass('hidden'); $(this).toggleClass('animated'); });});</script>
5、代码整体结构。
6、查看效果。
