这是一款效果非常炫酷的jQuery和CSS3堆叠卡片样式导航菜单特效。该导航菜单特效在用户点击汉堡包按钮的时候,各个子菜单会以卡片的形式堆叠排列在视口中,点击相应的子菜单就会切换到相应的页面上。
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); }); });
