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"></i></span>.zip<span class="size">11.5 MB</span></span></a></div> </div>
