• CSS3 Transitions属性打造动画的下载按钮特效


    一个网站的下载按钮应尽量吸引读者的注意。 这意味着网页设计师应该非常重视文件的下载界面。一个页面这么多的文件,如图片,视频和插件可以通过直接HTTP下载共享。许多免费网站甚至发布图标集和PSD文件供用户免费下载。在这些元素很多的网页下载按钮非常重要。下面就给大家带来一款动画的下载按钮,效果图如下:

    这里不需要任何JavaScript。我们需要的是引用一个外部的样式文件styles.css。这里所有的CSS文件和index.html文件在同一目录下面。

    html代码:

     <div id="wrapper">
            <h1>
                CSS3 Animated Download Buttons</h1>
            <div class="center">
                <a target=_blank href="http://www.w2bc.com/shili" class="dlbtn">Download<span class="details">.zip<span
                    class="size">11.5 MB</span></span></a></div>
            <br>
            <br>
            <div class="centerbig">
                <a target=_blank href="http://www.w2bc.com/shili" class="dlbtn big">Download<span class="details"><span
                    class="dlicon"><i class="entypo">&#59256;</i></span>.zip<span class="size">11.5 MB</span></span></a></div>
