CSS3实现的闪烁跳跃进度条~源码奉上
这个示例的原理是通过大量的css3属性来实现的,如:animation、transform、keyframes等等属性。值得注意的是这个示例采用了结构性伪类选择符E:nth-child(n),来进行对HTML元素的选择以及控制输出。相信这个伪类选择符在将来会是一个很强大的一个工具。推荐大家多多了解以及实践使用。这个伪类选择符E:nth-child(n)的含义是匹配父元素的第n个子元素E。 例如:ul li:nth-child(3)表示的是选择<ul>元素里面的第3个<li>。提示一下,该属性在IE8(包含IE8)版本以下是不支持的。
建议开发童鞋使用跨平台开发工具——统一开发环境UDE来进行查看、调试、开发哦~~它是一款HTML5跨平台一站式应用开发、调试和部署工具, 支持HTML5跨平台开发,原Java跨平台插件支持Android/Symbian/Kjava的跨平台和原生开发,为开发者提供丰富的应用模板、示例代码及开发者社区服务,已覆盖Android、iOS、WP、Symbian、Kjava操作系统平台。
下面就一起来看看该示例的实现代码吧。完整代码下载请见附件。
