使用方法

HTML结构

该导航菜单的HTML结构采用嵌套<div>的HTML结构，其中div.demo__close-menu是汉堡包按钮，每一个div.demo__section是一个子页面。

<div class="demo">   <div class="demo__close-menu"></div>   <div class="demo__section demo__section-1" data-section="1">     <div class="demo__menu-btn"></div>     <h2 class="demo__section-heading">Contact</h2>   </div>   <div class="demo__section demo__section-2 active" data-section="2">     <div class="demo__menu-btn"></div>     <h2 class="demo__section-heading">About</h2>   </div>   <div class="demo__section demo__section-3 inactive" data-section="3">     <div class="demo__menu-btn"></div>     <h2 class="demo__section-heading">Team</h2>   </div>   <div class="demo__section demo__section-4 inactive" data-section="4">     <div class="demo__menu-btn"></div>     <h2 class="demo__section-heading">Projects</h2>   </div> </div>

CSS样式

汉堡包图标按钮的样式如下：

.demo__close-menu {   position: absolute;   left: 22px;   top: 22px;   width: 29px;   cursor: pointer; } .demo__close-menu:before, .demo__close-menu:after {   content: "";   position: absolute;   left: 0;   top: 8px;   width: 100%;   height: 4px;   background: #7097B0; } .demo__close-menu:before {   -webkit-transform: rotate(45deg);           transform: rotate(45deg); } .demo__close-menu:after {   -webkit-transform: rotate(-45deg);           transform: rotate(-45deg); }

堆叠卡片页面的主要CSS样式如下：

.demo {   overflow: hidden;   position: absolute;   width: 100%;   height: 100%;   background: #CDDBEE;   border-radius: 6px; }   .demo__section {   z-index: 1;   position: absolute;   left: 0;   top: 0;   width: 100%;   height: 100%;   padding: 25px 0 0 65px;   border-radius: inherit;   -webkit-transition: -webkit-transform 0.4s;   transition: -webkit-transform 0.4s;   transition: transform 0.4s;   transition: transform 0.4s, -webkit-transform 0.4s;   -webkit-transform: translate3d(0, 0, 0);   transform: translate3d(0, 0, 0);   will-change: transform; }   .demo.menu-active .demo__section-1 {   -webkit-transform: translate3d(20px, 60px, 0);   transform: translate3d(20px, 60px, 0); }   .demo__section-1.inactive {   -webkit-transform: translate3d(100%, 60px, 0);   transform: translate3d(100%, 60px, 0); }   .demo.menu-active .demo__section-2 {   -webkit-transform: translate3d(40px, 120px, 0);   transform: translate3d(40px, 120px, 0); }   .demo__section-2.inactive {   -webkit-transform: translate3d(100%, 120px, 0);   transform: translate3d(100%, 120px, 0); }   .demo.menu-active .demo__section-3 {   -webkit-transform: translate3d(60px, 180px, 0);   transform: translate3d(60px, 180px, 0); }   .demo__section-3.inactive {   -webkit-transform: translate3d(100%, 180px, 0);   transform: translate3d(100%, 180px, 0); }   .demo.menu-active .demo__section-4 {   -webkit-transform: translate3d(80px, 240px, 0);   transform: translate3d(80px, 240px, 0); }   .demo__section-4.inactive {   -webkit-transform: translate3d(100%, 240px, 0);   transform: translate3d(100%, 240px, 0); }   .demo.menu-active .demo__section { cursor: pointer; }   .demo__section-heading {   text-transform: uppercase;   font-size: 12px;   -webkit-transition: -webkit-transform 0.4s;   transition: -webkit-transform 0.4s;   transition: transform 0.4s;   transition: transform 0.4s, -webkit-transform 0.4s; }   .demo.menu-active .demo__section-heading {   -webkit-transform: translateX(-45px);   transform: translateX(-45px); }

JavaScript

该特效中使用jQuery代码来处理汉堡包按钮的点击事件和堆叠卡片菜单的切换事件。

$(document).ready(function () {     var $demo = $('.demo');     var numOfSections = $('.demo__section').length;     $(document).on('click', '.demo__menu-btn', function () {         $demo.addClass('menu-active');     });     $(document).on('click', '.demo__close-menu', function () {         $demo.removeClass('menu-active');     });     $(document).on('click', '.demo.menu-active .demo__section', function () {         var $section = $(this);         var index = +$section.data('section');         $('.demo__section.active').removeClass('active');         $('.demo__section.inactive').removeClass('inactive');         $section.addClass('active');         $demo.removeClass('menu-active');         for (var i = index + 1; i <= numOfSections; i++) {             if (window.CP.shouldStopExecution(1)) {                 break;             }             $('.demo__section[data-section=' + i + ']').addClass('inactive');         }         window.CP.exitedLoop(1);     }); });
