1、新建html文档。
2、书写hmtl代码。<div class="container"> <div class="card-drop"> <a class='toggle' href="#"> <i class='fa fa-suitcase'></i> <span class='label-active'>百度经验</span> </a> <ul> <li class='active'> <a data-label="Everyting" href="#"><i class='fa fa-suitcase'></i> 百度经验</a> </li> <li> <a data-label="Design" href="#"><i class='fa fa-magic'></i> 百度经验特效</a> </li> <li > <a data-label="UI-UX" href="#"><i class='fa fa-bolt'></i> 百度经验特效</a> </li> <li> <a data-label="Print" href="#"><i class='fa fa-tint'></i> 百度经验特效</a> </li> <li> <a data-label="Photography" href="#"><i class='fa fa-camera-retro'></i> 网页特效</a> </li> <li> <a data-label="Photography" href="#"><i class='fa fa-camera-retro'></i> flash动画</a> </li> </ul> </div> </div>
3、初始化css代码。<style>html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video { margin: 0; padding: 0; border: 0; font: inherit; font-size: 100%; vertical-align: baseline; }html { line-height: 1; }ol, ul { list-style: none; }table { border-collapse: collapse; border-spacing: 0; }caption, th, td { text-align: left; font-weight: normal; vertical-align: middle; }q, blockquote { quotes: none; }q:before, q:after, blockquote:before, blockquote:after { content: ""; content: none; }a img { border: none; }article, aside, details, figcaption, figure, footer, header, hgroup, main, menu, nav, section, summary { display: block; }* { -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; }</style>
4、书写css代码。body { background-color: #ecf0f1; overflow: hidden; font-family: 'Roboto', sans-serif; font-size: 1em; }.container { max-width: 800px; margin: 0 auto; padding: 0 15px; }header { padding: 3.5rem 10%; background-color: #fff; margin-bottom: 2.5rem; text-align: center; }header svg { max-width: 50px; display: inline-block; fill: #1abc9c; vertical-align: middle; }header h1, header h2, header p { color: #2c3e50; margin-bottom: 1rem; }header h1 { font-weight: 300; color: #1abc9c; letter-spacing: -0.2rem; font-size: 4rem; text-shadow: 0 1px 0 rgba(255, 255, 255, 0.8); }header h2 { font-size: 1.5rem; margin-bottom: 0; }header h2 span { font-weight: 300; display: inlie-block; padding: 0 8px; font-size: 80%; color: #fff; -moz-border-radius: 4px; -webkit-border-radius: 4px; border-radius: 4px; }header h2 span.js { background-color: #E4A128; }header h2 span.css { background-color: #0070BB; }header h2 span.heart { background-color: #EB304A; }p { line-height: 1.8; text-align: left; font-weight: 300; font-size: 1.2rem; }.card-drop { position: relative; margin: 0 auto; -moz-perspective: 800px; -webkit-perspective: 800px; perspective: 800px; background: rgba(0, 0, 0, 0.1); }.card-drop a { display: block; width: 100%; padding: 20px 0 20px 20px; height: 60px; text-decoration: none; color: #217dbb; background-color: #fafafa; border: 1px solid #ddd; -moz-transition: all 0.3s ease-out; -o-transition: all 0.3s ease-out; -webkit-transition: all 0.3s ease-out; transition: all 0.3s ease-out; }.card-drop > a.toggle { position: relative; z-index: 100; -moz-backface-visibility: hidden; -webkit-backface-visibility: hidden; backface-visibility: hidden; -moz-transform-style: preserve-3d; -webkit-transform-style: preserve-3d; transform-style: preserve-3d; -moz-transform-origin: 50% 0%; -ms-transform-origin: 50% 0%; -webkit-transform-origin: 50% 0%; transform-origin: 50% 0%; -moz-transition: linear 0.1s; -o-transition: linear 0.1s; -webkit-transition: linear 0.1s; transition: linear 0.1s; }.card-drop > a.toggle:active { -moz-transform: rotateX(60deg); -webkit-transform: rotateX(60deg); transform: rotateX(60deg); }.card-drop > a.toggle:active:after { -moz-transform: rotateX(180deg); -webkit-transform: rotateX(180deg); transform: rotateX(180deg); }.card-drop > a.toggle:before, .card-drop > a.toggle:after { content: ""; position: absolute; }.card-drop > a.toggle:before { right: 25px; top: 50%; margin-top: -2.5px; border-left: 6px solid transparent; border-right: 6px solid transparent; border-top: 6px solid rgba(0, 0, 0, 0.8); }.card-drop > a.toggle.active:before { transform: rotate(180deg); }.card-drop ul { position: absolute; height: 100%; top: 0; display: block; width: 100%; }.card-drop ul li { margin: 0 auto; -moz-transition: all, ease-out 0.3s; -o-transition: all, ease-out 0.3s; -webkit-transition: all, ease-out 0.3s; transition: all, ease-out 0.3s; position: absolute; top: 0; z-index: 0; width: 100%; }.card-drop ul li a { border-top: none; }.card-drop ul li a:hover { background-color: #4aa3df; color: #f3f9fd; }.card-drop ul li.active a { color: #fff; background-color: #258cd1; cursor: default; }.card-drop ul li.closed a:hover { cursor: default; background-color: #3498db; }
5、书写并添加js代码。<script src="js/jquery-2.1.1.min.js"></script><script>(function ($) { var cards = $('.card-drop'), toggler = cards.find('.toggle'), links = cards.find('ul>li>a'), li = links.parent('li'), count = links.length, width = 100; li.each(function (i) { $(this).css('z-index', count - i); }); function setClosed() { li.each(function (index) { $(this).css('top', index * 4).css('width', width - index * 0.5 + '%').css('margin-left', index * 0.25 + '%'); }); li.addClass('closed'); toggler.removeClass('active'); } setClosed(); toggler.on('mousedown', function () { var $this = $(this); if ($this.is('.active')) { setClosed(); } else { $this.addClass('active'); li.removeClass('closed'); li.each(function (index) { $(this).css('top', 60 * (index + 1)).css('width', '100%').css('margin-left', '0px'); }); } }); links.on('click', function (e) { var $this = $(this), label = $this.data('label'); icon = $this.children('i').attr('class'); li.removeClass('active'); if ($this.parent('li').is('active')) { $this.parent('li').removeClass('active'); } else { $this.parent('li').addClass('active'); } toggler.children('span').text(label); toggler.children('i').removeClass().addClass(icon); setClosed(); e.preventDefault; });}(jQuery));</script>
6、代码整体结构。
7、查看效果。
