图像映射是将一些区域变成热点,我们在网上获取搜索图片,图片上会有关于任务的简短信息介绍,还有一个接触更多的就是QQ空间的相册,浏览QQ空间照片鼠标滑动到人物头像的时候让你选择标记人物,都是将图片和内容混合在一起进行表现。用户在看图片的时候不在是冰冷冷的图片,其实就是实现起来这种内容和图片的映射很简单,简单的看下效果:
Html代码:
<!-- 博客园-FlyElephant http://www.cnblogs.com/xiaofeixiang/ --> <div class="group-img"> <img src="../../public/images/group.jpg" alt="合影"> <ul> <li class="li"> <a href="http://www.cnblogs.com/xiaofeixiang/"> <span class="outer"> <span class="inner"> <span class="note">李连杰</span> </span> </span> </a> </li> <li class="yao"> <a href="http://www.cnblogs.com/xiaofeixiang/"> <span class="outer"> <span class="inner"> <span class="note">姚明</span> </span> </span> </a> </li> </ul> </div>
CSS代码:
.group-img { width: 423px; height: 480px; position: relative; } .group-img a { position: absolute; display: block; text-decoration: none; color: #000; border: 1px solid transparent; } .group-img a .outer { display: block; border: 1px solid transparent; } .group-img a .inner { display: block; width: 100px; height: 80px; border: 1px solid transparent; margin: 3px; } .group-img a .note { position: absolute; top: 100px; left: -9999px; background: #BDBDBD; width: 106px; padding: 5px; text-align: center; color: #fff; } .group-img .li a { top: 100px; left: 120px; } .group-img .yao a { top: 8px; left: 260px; } .group-img a:hover, .group-img a:focus { border: 1px solid #d4d82d; } .group-img a:hover .outer, .group-img a:focus .outer { border: 1px solid #00FF7F; } .group-img a:hover .inner, .group-img a:focus .inner { border: 1px solid #00CED1; } .group-img a:hover .note, .group-img a:focus .note { left: 0px; }
CSS布局需要注意两点将容器的大小和图片的大小保持一致,不显示的文字通过left隐藏文字,鼠标滑动的时候回归正常~
