jQuery/CSS3实现图片层叠展开特效

说说实现的方法和代码吧,主要由HTML、CSS以及jQuery代码组成。
HTML代码:
<div id="page_wrap"> <!--Stack 1 --> <div class="image_stack" style="margin-left:600px"> <img id="photo1" class="stackphotos" src="images/lanrenzhijia2.jpg" > <img id="photo2" class="stackphotos" src="images/lanrenzhijia3.jpg" > <img id="photo3" class="stackphotos" src="images/lanrenzhijia1.jpg" > </div> <!--Stack 2 --> <div class="image_stack" style="margin-left:300px"> <img id="photo1" class="stackphotos" src="images/lanrenzhijia4.jpg" > <img id="photo2" class="stackphotos" src="images/lanrenzhijia5.jpg" > <img id="photo3" class="stackphotos" src="images/lanrenzhijia6.jpg" > </div> <div class="single_photo"> <ul id="pics"> <li><a href="#pic1" title="Photo"><img src="images/lanrenzhijia3.jpg" alt="picture"></a></li> </ul> </div> </div>
把要用到的小图片列出来,HTML结构非常简单。
接下来是CSS,相对复杂一点,因为有用到CSS3相关的一些特性。
CSS代码:
.image_stack img { /* css style for photo stack */ border: none; text-decoration: none; position: absolute; margin-left:0px; width: 158px; height: 158px; } .image_stack { /* css style for photo stack */ width: 400px; position: absolute; margin:60px 10px 10px; } .image_stack img { /* css style for photo stack */ position: absolute; border: 4px solid #FFF; box-shadow: 2px 2px 8px rgba(0, 0, 0, 0.5); -moz-box-shadow: 2px 2px 8px rgba(0, 0, 0, 0.5); -webkit-box-shadow: 2px 2px 8px rgba(0, 0, 0, 0.5); z-index: 9999; /* Firefox */ -moz-transition: all 0.2s ease; /* WebKit */ -webkit-transition: all 0.2s ease; /* Opera */ -o-transition: all 0.2s ease; /* Standard */ transition: all 0.2s ease; } .image_stack #photo1 { /* position of last photo in the stack */ top: 8px; left: 108px; } .image_stack #photo2 {/* position of middle photo in the stack */ top: 6px; left: 104px; } .image_stack #photo3 {/* position of first photo at the top in the stack */ top: 4px; left: 100px; right: 100px; } .image_stack .rotate1 {/* rotate last image 15 degrees to the right */ -webkit-transform: rotate(15deg); /* safari and chrome */ -moz-transform: rotate(15deg);/*firefox browsers */ transform: rotate(15deg);/*other */ -ms-transform:rotate(15deg); /* Internet Explorer 9 */ -o-transform:rotate(15deg); /* Opera */ } .image_stack .rotate2 {/* css not used*/ -webkit-transform: rotate(0deg); /* safari and chrome */ -moz-transform: rotate(0deg);/*firefox browsers */ transform: rotate(0deg);/*other */ -ms-transform:rotate(0deg); /* Internet Explorer 9 */ -o-transform:rotate(0deg); /* Opera */ } .image_stack .rotate3 {/*rotate first image 15 degrees to the left*/ -webkit-transform: rotate(-15deg); /* safari and chrome */ -moz-transform: rotate(-15deg); /*firefox browsers */ transform: rotate(-15deg);/*other */ -ms-transform:rotate(-15deg); /* Internet Explorer 9 */ -o-transform:rotate(-15deg); /* Opera */ cursor: pointer; }
看出来了吧,主要是rotate实现图片翻转折叠的效果,另外指定了0.2s的ease动画。
jQuery代码:
$(document).ready(function() { $(".image_stack").delegate('img', 'mouseenter', function() {//when user hover mouse on image with div id=stackphotos if ($(this).hasClass('stackphotos')) {// // the class stackphotos is not really defined in css , it is only assigned to each images in the photo stack to trigger the mouseover effect on these photos only var $parent = $(this).parent(); $parent.find('img#photo1').addClass('rotate1');//add class rotate1,rotate2,rotate3 to each image so that it rotates to the correct degree in the correct direction ( 15 degrees one to the left , one to the right ! ) $parent.find('img#photo2').addClass('rotate2'); $parent.find('img#photo3').addClass('rotate3'); $parent.find('img#photo1').css("left","150px"); // reposition the first and last image $parent.find('img#photo3').css("left","50px"); } }) .delegate('img', 'mouseleave', function() {// when user removes cursor from the image stack $('img#photo1').removeClass('rotate1');// remove the css class that was previously added to make it to its original position $('img#photo2').removeClass('rotate2'); $('img#photo3').removeClass('rotate3'); $('img#photo1').css("left","");// remove the css property 'left' value from the dom $('img#photo3').css("left",""); });; });
其实jQuery也没什么事情,主要是动态为图片增加和删除类,用addClass和removeClass实现,这样鼠标滑过图片就可以翻转,鼠标离开图片又能够恢复,很不错吧。你也可以下载源代码研究。源码下载>>
