3D Folding Panel 是一款 CSS 转换和 jQuery 提供动力的次要内容面板。能够渲染 3D 褶皱效果。支持 IE、Chrome、firefox、Safari、Opera。
创建结构:
<main class="cd-main"> <ul class="cd-gallery"> <li class="cd-item"> <a href="item-1.html"> <div> <h2>Title 1</h2> <p>Lorem ipsum dolor sit amet, consectetur.</p> <b>View More</b> </div> </a> </li> <li class="cd-item"> <!-- content here --> </li> <!-- additional list items here --> </ul> <!-- .cd-gallery --> </main> <!-- .cd-main --> <div class="cd-folding-panel"> <div class="fold-left"></div> <!-- this is the left fold --> <div class="fold-right"></div> <!-- this is the right fold --> <div class="cd-fold-content"> <!-- content will be loaded using javascript --> </div> <a class="cd-close" href="#0"></a> </div> <!-- .cd-folding-panel -->
添加样式:
.cd-main { overflow-x: hidden; } .cd-main > * { transition: transform 0.5s 0.4s; } .cd-main.fold-is-open > * { /* on mobile - translate .cd-main content to the right when the .cd-folding-panel is open */ transform: translateX(100%); transition: transform 0.5s 0s; } .cd-folding-panel { position: fixed; top: 0; left: 0; width: 100%; height: 100vh; visibility: hidden; overflow: hidden; transition: visibility 0s 0.9s; } .cd-folding-panel .fold-left, .cd-folding-panel .fold-right { /* the :after elements of .fold-left and .fold-right are the 2 fold sides */ width: 100%; height: 100vh; overflow: hidden; /* enable a 3D-space for children elements */ perspective: 2000px; } .cd-folding-panel .fold-right { perspective-origin: 0% 50%; } .cd-folding-panel .fold-left { /* on mobile only the right fold side is visible */ display: none; } .cd-folding-panel .fold-right::after { /* 2 fold sides */ content: ''; position: absolute; top: 0; left: 0; height: 100%; width: 100%; transform-origin: right center; transform: translateX(-100%) rotateY(-90deg); transition: transform 0.5s 0.4s, background-color 0.5s 0.4s; } .cd-folding-panel.is-open { visibility: visible; transition: visibility 0s 0s; } .cd-folding-panel.is-open .fold-right::after { transform: translateX(0); transition: transform 0.5s 0s, background-color 0.5s 0s; } @media only screen and (min-width: 1100px) { .cd-item { width: 50%; float: left; transition: transform 0.5s 0.4s; } .fold-is-open .cd-item { transition: transform 0.5s 0s; transform: translateX(-400px); } .fold-is-open .cd-item:nth-of-type(2n) { transform: translateX(400px); } } @media only screen and (min-width: 1100px) { .cd-folding-panel { left: 50%; transform: translateX(-50%); width: 800px; } .cd-folding-panel .fold-left, .cd-folding-panel .fold-right { width: 50%; float: left; height: 100%; } .cd-folding-panel .fold-right { /* change perspective-origin so that the 2 fold sides have the same vanishing point */ perspective-origin: 0% 50%; } .cd-folding-panel .fold-right::after { transform-origin: right center; transform: translateX(-100%) rotateY(-90deg); } .cd-folding-panel .fold-left { display: block; /* change perspective-origin so that the 2 fold sides have the same vanishing point */ perspective-origin: 100% 50%; } .cd-folding-panel .fold-left::after { transform-origin: left center; transform: translateX(100%) rotateY(90deg); } .cd-folding-panel.is-open .fold-right::after, .cd-folding-panel.is-open .fold-left::after { transform: translateX(0); transition: transform 0.5s 0s, background-color 0.5s 0s; } } .cd-folding-panel .fold-right { perspective-origin: 0% 50%; } .cd-folding-panel .fold-left { perspective-origin: 100% 50%; }
事件处理:
/* open folding content */ $('.cd-gallery a').on('click', function(event){ event.preventDefault(); openItemInfo($(this).attr('href')); }); function openItemInfo(url) { /* check if mobile or desktop */ var mq = viewportSize(); if( $('.cd-gallery').offset().top > $(window).scrollTop() && mq != 'mobile') { /* if content is visible above the .cd-gallery - scroll before opening the folding panel */ $('body,html').animate({ 'scrollTop': $('.cd-gallery').offset().top }, 100, function(){ toggleContent(url, true); }); } else { toggleContent(url, true); } } function toggleContent(url, bool) { if( bool ) { /* load and show new content */ $('.cd-fold-content').load(url+' .cd-fold-content > *', function(event){ $('body').addClass('overflow-hidden'); $('.cd-folding-panel').addClass('is-open'); $('.cd-main').addClass('fold-is-open'); }); } else { /* close the folding panel */ $('.cd-folding-panel').removeClass('is-open') $('.cd-main').removeClass('fold-is-open'); /* ...*/ } }
