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。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | < 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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | .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( 45 deg); transform: rotate( 45 deg); } .demo__close-menu:after { -webkit-transform: rotate( -45 deg); transform: rotate( -45 deg); } |
堆叠卡片页面的主要CSS样式如下:

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。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | $(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); }); }); |
