纯CSS3实现的图片滑块程序 效果非常酷 - html/css语

之前我们经常会看到很多利用jQuery实现的焦点图插件,种类太多了,今天我想给大家分享一款利用纯CSS3实现的图片滑块应用,完全是利用CSS3的相关特性,没有使用JS,个人觉得还是挺不错的,先来看看效果图:       看上去挺不错的吧,简洁、清新、大气。   当然我们也可以在这里查看DEMO演示。   接下来我们一起来分析一下 源码,首先是HTML代码,非常简单:   复制代码 <div id="gal">   <nav class="galnav">     <ul>         <li><input type="radio" name="btn" value="one" checked="checked" />         <label for="btn"></label>         <figure>           <img src="images/01_Fabio_Basile.jpg" />           <figcaption>             <h4>Fabio Basile</h4>               <nav role='navigation'>                 <p>iPhone 6 Infinity</p>         <ul>             <li><a href="#" class="entypo-dribbble">             </a></li>             <li><a href="#" class="entypo-twitter"></a>             </li>         </ul>               </nav>             </figcaption>         </figure>           </li>         <li><input type="radio" name="btn" value="two" /> <label for="btn">         </label>          <figure class="entypo-forward">           <img src="images/08_Brian_Miller.jpg" />           <figcaption>             <h4>Brian Miller</h4>               <nav role='navigation'>                 <p>TypeTi.me</p>         <ul>             <li><a href="#" class="entypo-dribbble"></a>             </li>             <li><a href="#" class="entypo-twitter"></a>             </li>         </ul>               </nav>             </figcaption>         </figure>           </li>         <li><input type="radio" name="btn" value="three" /> <label for="btn">         </label>         <figure class="entypo-forward">           <img src="images/05_Nicolas_Quod.jpg" />           <figcaption>             <h4>Nicolas Quod</h4>               <nav role='navigation'>                 <p>Iphone 6 - Notification - iOS 7</p>         <ul>             <li>             <a href="#" class="entypo-dribbble">             </a></li>             <li>             <a href="#" class="entypo-twitter">             </a></li>         </ul>               </nav>             </figcaption>         </figure>           </li>         <li><input type="radio" name="btn" value="four" /> <label for="btn">         </label>          <figure class="entypo-forward">           <img src="images/04_Joffrey.jpg" />           <figcaption>             <h4>Joffrey</h4>               <nav role='navigation'>                 <p>鈻?/p&gt; </p>         <ul>             <li><a href="#" class="entypo-dribbble">             </a></li>             <li><a href="#" class="entypo-twitter">             </a></li>         </ul>               </nav>             </figcaption>         </figure>           </li>         <li><input type="radio" name="btn" value="five" /> <label for="btn">         </label>          <figure class="entypo-forward">           <img src="images/09_Jared_Long.jpg" />           <figcaption>             <h4>Jared Long</h4>               <nav role='navigation'>                 <p>Don&#39;t drop your iPhone Infinity</p>         <ul>             <li>             <a href="#" class="entypo-dribbble">             </a></li>             <li>             <a href="#" class="entypo-behance">             </a></li>         </ul>               </nav>             </figcaption>         </figure>           </li>         <li><input type="radio" name="btn" value="six" /> <label for="btn">         </label>          <figure class="entypo-forward">           <img src="images/02_Charles_Treece.jpg" />           <figcaption>             <h4>Charles Treece</h4>               <nav role='navigation'>                 <p>iPhone 6 Infinity Side Status Bar</p>         <ul>             <li>             <a href="#" class="entypo-dribbble">             </a></li>             <li>             <a href="#" class="entypo-twitter">             </a></li>         </ul>               </nav>             </figcaption>         </figure>           </li>     </ul>   </nav> </div> 复制代码 这些HTML代码只是构造了几张图片,等一下可以切换。另外,每张图片都放置一个radio,这个radio来充当切换按钮。   接下来就是CSS代码了:   复制代码 *, *:before, *:after {   margin:0;   padding:0;   -webkit-box-sizing:border-box;   -moz-box-sizing:border-box;   box-sizing:border-box; } #gal {   position:relative;   width:600px;   height:300px;   margin:0 auto;   top:100px;   background:white;

  -o-transition:width .1s;   transition:width .1s; } h2 a:hover:after {   width:100%; } body {background:#f0f0f0;} html, body {   width:100%;   height:100%; } 复制代码 这个 CSS代码相对比较复杂,重点在这个地方:   利用label重写radio的样式,但是又能完成点击label就像点击radio一样的效果,核心代码如下:   复制代码 input[type="radio"], input[type="radio"] + label {   position:absolute;   bottom:15px;   display:block;   width:20px;   height:20px;   -webkit-border-radius:50%;   -moz-border-radius:50%;   border-radius:50%;   cursor:pointer; } input[type="radio"] {   opacity:0;   z-index:9; } input[value="one"], input[value="one"] + label {left:20px;} input[value="two"], input[value="two"] + label {left:128px;} input[value="three"], input[value="three"] + label {left:236px;} input[value="four"], input[value="four"] + label {left:344px;} input[value="five"], input[value="five"] + label {left:452px;} input[value="six"], input[value="six"] + label {right:20px;} input[type="radio"] + label {   background:rgba(255,255,255,0.35);   z-index:7;   -webkit-box-shadow:0px 0px 0px 0px rgba(255,255,255,0.15);   -moz-box-shadow:0px 0px 0px 0px rgba(255,255,255,0.15);   box-shadow:0px 0px 0px 0px rgba(255,255,255,0.15);   -webkit-transition:all .3s;   -moz-transition:all .3s;   -o-transition:all .3s;   transition:all .3s; }
