纯CSS3实现的图片滑块程序,效果非常酷
接下来我们一起来分析一下源码,首先是HTML代码,非常简单:
- <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>
- </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 href="#" class="entypo-twitter">

- </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>

- </figcaption>
- </figure>
- </li>
- </ul>
- </nav>
- </div>
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:

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:
- 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;
- }
